  • Conflicting Data on the Incidence of Leukopenia and Neutropenia After
           Heated Intraperitoneal Chemotherapy with Mitomycin C
    • Authors: Yael Feferman; Shanel Bhagwandin; Joseph Kim; Samantha N. Aycart; Daniela Feingold; Daniel M. Labow; Umut Sarpel
      Abstract: Background During heated intraperitoneal chemotherapy (HIPEC), neutropenia rates of 20 to 40% have been reported when mitomycin C (MMC) is dosed by weight or body surface area (BSA). This study investigated the authors’ HIPEC experience using a fixed 40-mg dose of MMC, per consensus guidelines, and analyzed predictors for severe leukopenia and neutropenia. Methods Patients who underwent MMC-HIPEC from 2007 to 2016 at a single tertiary care center were retrospectively reviewed. Results Among 314 MMC-HIPEC cases, 72 patients in the early era of the authors’ program received routine prophylactic postoperative granulocyte-colony-stimulating factor (GCSF). This early cohort had five severe leukopenic reactions and one neutropenic reaction. In the subsequent 242 cases without GCSF prophylaxis, severe leukopenia developed in 16 patients (7%), with neutropenia occurring in 11 (4.5%) of these cases. A history of prior systemic chemotherapy was noted in 9 (56%) of the 16 leukopenic patients compared with 112 (46%) of the patients who had no leukopenia (nonsignificant difference). The median nadir of leukopenia was 5 days (range 1–11 days). Of the 11 neutropenic patients, 6 received therapeutic GCSF, and 5 recovered without intervention. The 30-day postoperative mortality of the patients with leukopenia was 0%. Conclusion In this study, the incidence of neutropenia after HIPEC with 40 mg of MMC was markedly lower than reported in the literature for doses adjusted by BSA or weight. The authors report that GCSF is not necessary for routine prophylaxis of all MMC-HIPEC patients. The findings suggest that a fixed 40-mg dose of MMC allows HIPEC to be performed with less risk of immunosuppression.

  • Recurrence of Optimally Treated Malignant Peritoneal Mesothelioma with
           Cytoreduction and Heated Intraperitoneal Chemotherapy
    • Authors: Danielle R. Heller; Cody Chiuzan; Robert N. Taub; Joshua C. Leinwand; Allison M. Greene; Gleneara E. Bates; John A. Chabot; Michael D. Kluger
      Abstract: Background The prognosis for patients with diffuse malignant peritoneal mesothelioma has dramatically improved with cytoreductive surgery and intraperitoneal chemotherapy. Little is known about disease recurrence after treatment. We analyzed the time to and predictors of recurrence in a large cohort of optimally treated patients. Methods We examined 113 patients completing a two-stage cytoreduction and intraperitoneal chemotherapy protocol. All patients achieved optimal surgical resection with completeness of cytoreduction (CC) score ≤ 1 and were divided into two groups based on absence (Group A) or presence (Group B) of gross disease at the outset of the second operation. Predictors of disease recurrence and recurrence-free survival (RFS) were determined using Cox proportional hazard regression modeling, and estimates were obtained by using the Kaplan–Meier method. Results Forty-six percent of patients had no gross evidence of disease at the second operation; the remaining 54% were cytoreduced to CC ≤ 1 (Group B). Forty-two percent of patients developed disease recurrence with a median recurrence-free survival of 38.5 months for the cohort; 79% of these received a form of iterative treatment. There was no statistically significant difference in recurrence-free survival between Group A (median RFS: 44.6 months) and B (median RFS: 35.5 months) (log-rank test, p = 0.06). Additionally, the only variable significantly associated with RFS was male gender (hazard ratio [HR] 1.98, 95% confidence interval [CI] 1.16–3.38). Conclusions Absence of gross disease at the second operation was not statistically protective against recurrence compared with presence of quantifiable residual disease (Group B) that was effectively cytoreduced. Long-term disease surveillance is recommended, because recurrence continues years after treatment. Where a question of recurrence arises on surveillance, males may benefit from a higher degree of suspicion.

    • Authors: Emilio Vicente; Yolanda Quijano; Benedetto Ielpo; Hipolito Duran; Eduardo Diaz; Isabel Fabra; Luis Malavé; Valentina Ferri; Sara Lazzaro; Denis Kalivaci; Riccardo Caruso
      Abstract: Background Hepatic resection of tumors invading the retrohepatic vena cava and hepatic veins are a challenge for surgeons, who consider them unresectable most of the time.1 , 2 Ex situ hepatectomy and liver autotransplantation has developed to improve resectability of these malignancies.3,4 Methods The patient was a 51-year-old man who had jaundice secondary to a intrahepatic cholangiocarcinoma 7 cm in diameter in the right lobe of the liver and the caudate lobe. A volumetric scan showed a future liver remnant (segments 2 and 3) not sufficient according to the body weight. The patient was considered to be unresectable by conventional resection due to the critical invasion to the retrohepatic vena cava together with the three hepatic veins. Therefore, an ex vivo extended right hepatectomy and autotransplantation were indicated. Results The patient underwent biliary decompression through a percutaneous transhepatic catheter and right portal vein embolization for left lobe hypertrophy. During the surgery, the liver was removed with the retrohepatic vena cava, which was replaced by a prosthetic graft without a veno-venous bypass. Ex vivo extended right hepatectomy was performed, and a prosthetic graft was used to replace the vena cava where the remaining left hepatic vein was anastomosed. The surgery duration was 9 h, and the anhepatic time was 4.5 h. The postoperative hospital stay was 19 days, and at this writing, 3 years later, the patient is disease-free. Conclusion Ex vivo hepatectomy without veno-venous bypass should be considered a valid therapeutic option for selected patients with cholangiocarcinoma invading the retrohepatic vena cava.

  • Isolated Limb Perfusion and Infusion for Extremity Soft Tissue Sarcoma: A
           Contemporary Systematic Review and Meta-Analysis
    • Authors: Madalyn G. Neuwirth; Yun Song; Andrew J. Sinnamon; Douglas L. Fraker; Jonathan S. Zager; Giorgos C. Karakousis
      Abstract: Background Isolated limb perfusion (ILP) and isolated limb infusion (ILI) have been variably used in recent years for the treatment of locally advanced or marginally resectable extremity soft tissue sarcomas (STSs). We performed a systematic review and meta-analysis of contemporary studies to further characterize treatment patterns and outcomes. Methods PubMed was queried for articles published in or after the year 2000, in the English language, with > 10 patients, and with adequate outcome data following ILP/ILI. Descriptive aggregate statistics were performed. Results Nineteen studies that met the inclusion criteria were identified, with a total of 1288 patients. Weighted mean patient age was 55.9 years and 52% were male. The majority underwent ILP (88%) versus 12% for ILI, and chemotherapeutic regimens used were as follows: (1) melphalan with tumor necrosis factor (TNF)-α (78%), (2) melphalan ± actinomycin (10%), and (3) other regimens (12%). Most common histologies treated were malignant fibrous histiocytoma (21%), liposarcoma (16%), synovial (11%) and leiomyosarcoma (7%). Aggregate overall response rate (ORR) post-procedure was 73.3%, with 25.8% demonstrating a complete response (CR). Similar unadjusted ORRs were noted in the melphalan treatment groups with and without TNFα (72.0 and 67.0%, respectively; p = 0.27). Grade III toxicity was observed in 15.4% of patients, and grade IV/V toxicity was observed in 6.0% of patients. Overall limb salvage rate was 73.8% and median time to local (in-field) progression ranged from 4 to 28 months (weighted median 22.1 months). Conclusion ILP and ILI for extremity STS can be safely performed with appreciable response rates and significant limb salvage rates. Further study is needed to identify optimal treatment regimens by histology.

  • High Expression of the Mitophagy-Related Protein Pink1 is Associated with
           a Poor Response to Chemotherapy and a Poor Prognosis for Patients Treated
           with Neoadjuvant Chemotherapy for Esophageal Squamous Cell Carcinoma

      Abstract: Background Autophagy plays a major role in cellular homeostasis and is implicated in cancer progression. Damaged mitochondria are scavenged and eliminated by mitochondrial autophagy, referred to as mitophagy, which can promote cancer cell survival. This study investigated the expression and effects of the autophagy-related protein LC3 and the mitophagy-related protein Pink1 in human esophageal squamous cell carcinoma (ESCC). Methods Both LC3 and Pink1 were analyzed by immunohistochemistry in tissues from 217 ESCC patients, including 159 patients undergoing neoadjuvant chemotherapy. The relationships between LC3 and Pink1 expression and various clinicopathologic factors were determined. In vitro assays were performed to assess the role of LC3 and Pink1 in ESCC chemoresistance. Results High LC3 expression was observed in 47.9% and high Pink1 expression in 48.4% of the ESCC patients. Pink1 expression was significantly higher in patients who underwent chemotherapy than in patients who did not (p = 0.032). High LC3 and Pink1 expression was significantly correlated with poor response to chemotherapy (p = 0.004 and p < 0.001, respectively), and high expression of Pink1, but not LC3, was significantly correlated with a poor prognosis for patients treated with preoperative chemotherapy (p = 0.007). Multivariate analysis identified Pink1 expression as an independent prognostic factor (p = 0.042). In vitro assays demonstrated that LC3-II and Pink1 expression increased after chemotherapeutic treatment in the ESCC cell line, and inhibition of autophagy and mitophagy using chloroquine and siPink1, respectively, restored chemosensitivity. Conclusions High expression of Pink1 is associated with chemoresistance and a poor prognosis for ESCC patients undergoing neoadjuvant chemotherapy.

      Abstract: Background This phase III study was undertaken to evaluate the efficacy of an allogeneic whole-cell vaccine (Canvaxin™) plus bacillus Calmette-Guerin (BCG) after complete resection of stage IV melanoma. Methods After complete resection of ≤5 distant metastases, patients were randomly assigned to BCG+Canvaxin (BCG/Cv) or BCG+placebo (BCG/Pl). The primary endpoint was overall survival (OS); secondary endpoints were disease-free survival (DFS), and immune response measured by skin test (ClinicalTrials.gov identifier: NCT00052156). Results Beginning in May 1998, 496 patients were randomized. In April 2005, the Data Safety Monitoring Board recommended stopping enrollment due to a low probability of efficacy. At that time, median OS and 5-year OS rate were 38.6 months and 44.9%, respectively, for BCG/Pl versus 31.4 months and 39.6% in the BCG/Cv group (hazard ratio (HR), 1.18; p = 0.250). Follow-up was extended at several trial sites through March 2010. Median OS and 5-year and 10-year survival was 39.1 months, 43.3 and 33.3%, respectively, for BCG/Pl versus 34.9 months, 42.5 and 36.4%, in the BCG/Cv group (HR 1.053; p = 0.696). Median DFS, 5- and 10-year DFS were 7.6 months, 23.8 and 21.7%, respectively, for BCG/Pl versus 8.5 months, 30.0%, and 30.0%, respectively, for the BCG/Cv group (HR 0.882; p = 0.260). Positive DTH skin testing correlated with increased survival. Discussion In this, the largest study of postsurgical adjuvant therapy for stage IV melanoma reported to date, BCG/Cv did not improve outcomes over BCG/placebo. Favorable long-term survival among study patients suggests that metastasectomy should be considered for selected patients with stage IV melanoma.

  • Frailty Correlates with Postoperative Mortality and Major Morbidity After
           Cytoreductive Surgery with Hyperthermic Intraperitoneal Chemotherapy
    • Authors: Ioannis T. Konstantinidis; Konstantinos Chouliaras; Edward A. Levine; Byrne Lee; Konstantinos I. Votanopoulos
      Abstract: Background Frailty is increasingly being recognized as a powerful predictor of postoperative outcomes for cancer patients. This study examined the role of the modified frailty index (MFI) in predicting outcomes for patients undergoing cytoreduction (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC). Methods Data from National Surgical Quality Improvement Program (NSQIP) patients who underwent CRS/HIPEC between 2005 and 2014 were reviewed. The MFI, validated for use in NSQIP, was used to determine correlation between frailty and postoperative outcomes. Results The analysis included 1171 patients. The patients were divided into three groups: non-frail (MFI 0), mildly frail (MFI 1 or 2), or severely frail (MFI ≥ 3). More than 90% of patients had an MFI of 0 or 1. The MFI was 0 for 716 patients (61.1%), 1 for 373 patients (31.9%), 2 for 76 patients (6.5%), 3 for 5 patients (0.4%), and 4 for 1 patient (0.1%). Overall, grade 4 Clavien morbidity was observed in 99 patients (8.5%) and mortality in 26 patients (2.2%). For non-frail, mildly frail, and severely frail patients, worsening frailty correlated respectively with increases in grade 4 Clavien morbidity (6.7% vs. 10.9% vs. 33.3%; p = 0.004) and mortality (1.3% vs. 3.3% vs. 33.3%; p < 0.001). In the multivariate analysis, which included age of 70 years or older and albumin level of 3 or lower, frailty was the only factor that correlated with postoperative mortality: non-frail:reference, mildly frail [odds ratio (OR) 2.76, 95% confidence interval (CI) 1.14–6.73; p = 0.025], severely frail (OR 29.1, 95% CI 4–210.87; p = 0.01), age of 70 years or older (OR 1.16, 95% CI 0.34–3.93; p = 0.81), and albumin level of 3 or lower (OR 2.42, 95% CI 0.84–6.98; p = 0.1). Conclusions Frailty is a strong predictor of major grade 4 morbidity and mortality after CRS/HIPEC. Severe frailty should be a relative contraindication to CRS/HIPEC. Frailty correlates should be a selection factor in the evaluation of all candidates for CRS/HIPEC.

      Abstract: Background Cytoreductive surgery and hyperthermic intraperitoneal chemoperfusion (CRS-HIPEC) is a complex procedure that often requires ostomy creation to protect high-risk anastomoses. This study aimed to evaluate the authors’ institutional experience with CRS-HIPEC-associated ostomies, determine predictors of ostomy creation and reversal, and assess their impact on survival. Methods The study analyzed clinicopathologic, perioperative, and oncologic data from a prospective database of 1435 CRS-HIPEC procedures for peritoneal metastases. The Kaplan–Meier method was used to estimate survival. Multivariate analyses identified associations with ostomy creation/reversal and survival. Results Ostomies were created in 34% of the patients, most commonly loop ileostomies (82%). Loop ileostomies were reversed in the majority of patients (83%), whereas non-loop ileostomies were infrequently reversed (< 10% reversal rate). In a multivariate logistic regression model, intermediate or high tumor grade, colectomy/proctectomy, longer operative time, and lower Charlson comorbidity index were associated with loop ileostomy creation, whereas incomplete macroscopic resection, colorectal histology, and major postoperative complications were associated with non-reversal of loop ileostomy. In a multivariate Cox proportional hazards model, intermediate or high tumor grade and non-reversal of loop ileostomy were associated with worse overall survival. Conclusions Loop ileostomies were almost always reversed, whereas non-loop ileostomies were almost always permanent. Hospital readmissions for loop ileostomy-related complications were common. Therefore, formal outpatient protocols for prevention and management should be implemented. Non-reversal of loop ileostomy was associated with very poor survival.

      Abstract: Background Isolated limb infusion (ILI) is a minimally invasive technique for delivering regional chemotherapy to an extremity for patients with locally advanced cutaneous malignancies and sarcoma. Methods A single-institution, prospectively collected database was analyzed for intention-to-treat with ILI. Results From 2007 to 2016, 163 patients underwent 205 procedures (201 were successfully completed), and four malignancies were treated: melanoma (72.1% of all ILIs), sarcoma (23.4%), squamous cell carcinoma (SCC; 2.0%) and Merkel cell carcinoma (MCC; 2.5%). A median grade II regional Wieberdink toxicity score was observed, with 88.1% of patients experiencing grade II or less. Median follow-up was 21.8 months, and overall response rate (ORR) was 59.0% for melanoma, 48.9% for sarcoma, 50.0% for SCC, and 60.0% for MCC. A significant difference (p = 0.04) between upper (76.9%) and lower extremity (55.1%) ORR was observed in patients with melanoma. When comparing responders with nonresponders, patients with melanoma had significantly longer in-field progression-free survival (IPFS; 14.1 vs. 3.2 months, p < 0.001), distant metastatic-free survival (DMFS; not reached vs. 25.8 months, p = 0.006), and overall survival (OS; 56.0 vs. 26.7 months, p = 0.0004). Sarcoma responders had a significantly longer IPFS (13.0 vs. 2.7 months, p < 0.0001), but no significant distant metastatic or OS advantage. Over a median follow-up of 19.3 months, sarcoma patients had an overall limb salvage rate of 68.4%. Conclusion ILI is a well-tolerated procedure for patients with locally advanced melanoma, sarcoma, and other cutaneous malignancies. ILI responders had a significantly longer time to IPFS, while melanoma responders also had a DMFS and OS advantage.

  • Antimicrobial Properties of Perfusate Fluid After Cytoreductive Surgery
           
    • Authors: Krystle N. Lange; Danielle McKay; Brian G. Gentry; Jan Franko
      Abstract: Background Infectious postoperative complications often delay systemic chemotherapy after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CS-HIPEC). Because the authors have empirically observed fewer incisional infectious complications than expected after CS-HIPEC with mitomycin C (MMC), they investigated the antimicrobial properties of HIPEC perfusate fluid. Methods This study prospectively measured in vitro bacterial growth inhibition by HIPEC perfusate (n = 18). After 10 µL of perfusate had been plated on agar plate inoculated by standard strains of either Escherichia coli (strain 25922) or Staphylococcus aureus (strain 25923), it was incubated at 37 °C for 24 h. Antimicrobial activity evidenced by a zone of complete growth inhibition was measured in millimeters. These were compared against growth inhibition produced by control groups represented by MMC solution in normal saline (MMC concentrations of 2, 4, 6, 8, and 8.75 µg/mL), 7 per group. Results Bacterial inhibition by HIPEC perfusate was stronger against E. coli than against S. aureus (13.1 ± 6.8 vs 8.3 ± 7.7 mm; p = 0.005). No E. coli inhibition was observed for MMC saline in concentrations of 2 through 8 µg/mL (p < 0.001 each), and inhibition of 4.5 ± 5.7 mm was observed for an MMC saline concentration of 8.75 µg/mL (p = 0.007). The S. aureus inhibition zones by MMC saline solutions were 2.2 ± 2.1 (p = 0.002), 5.1 ± 2.3 (p = 0.135), 7.5 ± 1.0 (p = 0.654), 9.6 ± 0.9 (p = 0.058), and 10.2 ± 0.4 mm (p = 0.021). Conclusion The antimicrobial properties of HIPEC perfusate are considerable but variable between patients and stronger against E. coli than against S. aureus. Further studies of HIPEC carrier solutions and chemotherapy agents may result in reduction of surgical-site infection and thus enhanced patient recovery.

  • Total Mesenteric Peritonectomy for Peritoneal Metastases (with video)
    • Authors: Jean-Baptiste Cazauran; Antoinette Lasseur; Arnaud Pasquer; Pascal Rousset; Jeremy Guedj; Guillaume Passot; Olivier Glehen
      Abstract: ABSTRACT Background Complete cytoreductive surgery (CRS), combining organ resection and peritonectomy, is the only potentially curative treatment for patients with peritoneal metastases (PM).1 , 2 Diffuse mesenteric PM usually represents a contraindication for CRS.3 This report presents a standardized total mesenteric peritonectomy, which provides a therapeutic option of complete CRS for patients with diffuse mesenteric PM. Patient A 73-year-old man had a diagnosis of PM caused by an urachal adenocarcinoma (signet cell type). Initial assessment found a 60-mm urachal tumor above the dome of the urinary bladder. Dedicated magnetic resonance imaging (MRI)4 and explorative laparoscopy confirmed the presence of diffuse mucinous PM suspected of pseudomyxoma peritonei arising from urachus. The patient was treated by a systemic induction chemotherapy including cisplatin, fluorouracil, and docetaxel, with an almost full regression of the PM shown on control MRI. The man then was treated with CRS and hyperthermic intraperitoneal chemotherapy.5 Technique Exploration found persistent diffuse macro-nodular PM with a good response to chemotherapy, a 16/39 peritoneal cancer index,6 and no digestive tract or other organ involvement. The CRS procedure included complete urachus resection, together with appendicectomy, cholecystectomy, omentectomy, and a total parietal and mesenteric peritonectomy, with a completeness of cytoreduction score6 of 1, as illustrated in the video. At this writing, after 6 months of follow-up evaluation, the patient remains free of symptomatic peritoneal disease or local recurrence. Conclusion Total mesenteric peritonectomy can be safely performed with the reported technique irrespective of how widespread PM is along the mesentery as long as few small bowel serous membranes are involved.

  • The Surgical Apgar Score Predicts Not Only Short-Term Complications But
           Also Long-Term Prognosis After Esophagectomy
    • Authors: Akio Nakagawa; Tetsu Nakamura; Taro Oshikiri; Hiroshi Hasegawa; Masashi Yamamoto; Shingo Kanaji; Yoshiko Matsuda; Kimihiro Yamashita; Takeru Matsuda; Yasuo Sumi; Satoshi Suzuki; Yoshihiro Kakeji
      Abstract: Background The surgical Apgar score (SAS) quantifies three intraoperative factors and predicts postoperative complications, but few reports describe its usefulness in esophagectomy, and no studies to date show its correlation with long-term prognosis after esophagectomy. Methods This study investigated 400 cases in which esophagectomy was performed on esophageal malignant tumors at the authors’ hospital from January 2007 to January 2017. In this study, SAS was defined as the sum of the scores of three parameters, namely, estimated blood loss, lowest mean arterial pressure, and lowest heart rate, with values extracted from medical records. Postoperative complications classified as Clavien–Dindo grade 3 or higher were also extracted. The study retrospectively compared the relationship of SAS to postoperative complications and survival. Results Univariate analysis showed that postoperative complications were significantly associated with hypertension (p = 0.017), thoracotomy (p = 0.012), and SAS ≤ 5 (p < 0.0001), and multivariate analysis showed that hypertension (p = 0.049) and SAS ≤ 5 (p < 0.0001) were significant predictive factors for complications. In the prognostic analysis, log-rank analysis showed that patients with an SAS ≤ 5 had a significantly poorer prognosis than those with a SAS > 5 (p = 0.043), especially for complications classified as clinical stage 2 or higher (p = 0.027). In the multivariate analysis, SAS ≤ 5 was identified as a significantly poor prognostic factor for complications classified as clinical stage 2 or higher (p = 0.029). Conclusion In this study, SAS was useful not only for predicting short-term complications, but also as a long-term prognostic factor after esophagectomy.

  • Cross-Sectional Location of Gastric Cancer Affects the Long-Term Survival
           of Patients as Tumor Invasion Deepens
    • Authors: Yoon Ju Jung; Ho Seok Seo; Ji Hyun Kim; Cho Hyun Park; Han Hong Lee
      Abstract: Background The prognosis of gastric cancer is generally determined by tumor depth and lymph node metastasis, while the effect of cross-sectional tumor location on prognosis remains unclear. Methods This study recruited patients who had been diagnosed with gastric cancer and who underwent gastrectomy from 1989 to 2012. The cross-sectional locations of the gastric cancers were classified into four regions: the lesser (LC) and greater curvatures (GC), and anterior (AW) and posterior walls (PW). Results Overall, 4820 patients were enrolled in this study. The most common site of gastric cancer among the four cross-sectional locations was the LC (46.4%), while the proportions of PW (19.9%), AW (18.4%), and GC (15.4%) were similar. Overall survival differed statistically (p = 0.013) according to the cross-sectional location, and the 5-year overall survival of those with tumors with a GC location was significantly worse (p = 0.003) than for the other three locations. In subgroup multivariate analysis, GC location was an independent prognostic indicator for a worse clinical outcome at T stage 3–4b (hazard ratio 1.365, 95% confidence interval 1.150–1.620, p < 0.001). In addition, a GC gastric cancer had a higher recurrence rate in terms of peritoneal seeding compared with other locations. Conclusions The cross-sectional location of gastric cancer is associated with long-term survival. A GC location predicts a worse prognosis, especially in gastric cancer patients with deeper T stages.

      Abstract: Background The prognostic impact of pathologic response to preoperative therapy on patients with duodenal adenocarcinoma (DA) and ampullary adenocarcinoma (AMPA) has not been established. Methods A retrospective review of 266 patients who underwent curative resection for DA (n = 97) or AMPA (n = 169) during 1993–2015 was performed. For patients who underwent preoperative therapy, the pathologic response was systematically evaluated and classified as major (0–49% of viable residual tumor cells) or minor (≥ 50% of viable residual tumor cells). Uni- and multivariable analyses were performed to identify predictors of pathologic response and disease-specific survival (DSS). Results For the 79 patients treated with preoperative therapy (DA: n = 34; AMPA: n = 45), concomitant use of radiation (80%, 67/79) was the sole independent predictor of major pathologic response (odds ratio [OR] 8.17; 95% confidence interval [CI] 1.85–58.2; P = 0.005). The patients with major pathologic response had a better 5-year DSS rate than the patients with minor pathologic response (DA: 65 vs 25%; P = 0.028; AMPA: 85 vs 43%; P = 0.016). In the multivariable analysis of DSS for the 79 patients who underwent preoperative therapy, major pathologic response was the sole predictor of improved DSS (hazard ratio [HR] 2.88; 95% CI 1.41–5.98; P = 0.004). In the multivariable analysis of DSS for the entire cohort, pathologic stage 2 or lower was the sole predictor of better DSS. Conclusion The major pathologic response to preoperative therapy predicted improved DSS after resection of DA and AMPA and might represent a new prognosticator after resection of DA and AMPA.

  • Outcome with Primary En-bloc Esophagectomy for Submucosal Esophageal
           Adenocarcinoma
    • Authors: Katrin Schwameis; Kyle M. Green; Stephanie G. Worrell; Jamil Samaan; Shannon Cooper; Sergei Tatishchev; Daniel S. Oh; Jeffrey A. Hagen; Steven R. DeMeester
      Abstract: Background Intramucosal esophageal adenocarcinoma can be reliably treated endoscopically. Controversy exists about the use of endotherapy versus esophagectomy for submucosal tumors. Increasingly endotherapy is considered for submucosal tumors in part because of the presumed high mortality with esophagectomy and the perceived poor prognosis in patients with nodal disease. This study was designed to assess survival following primary en bloc esophagectomy (EBE) in patients with submucosal esophageal adenocarcinoma (EAC). Methods This is a retrospective review of all patients who underwent EBE for submucosal EAC between 1998 and 2015. No patient had neoadjuvant therapy. Results There were 32 patients (28M/4F; median age 64 years). The median tumor size was 1.5 cm (0.4–8.0), and the median number of resected nodes was 48 (23–85). There was one perioperative death. Lymph node metastases were present in 7 patients (22%). There was one involved node in four patients and 2, 3, and 31 nodes in one patient each. The one N3 patient received adjuvant therapy. The median follow-up was 87 months. Overall survival at 5 and 10 years was 84 and 70% respectively. Disease-specific survival at 10 years was 90%. Eight patients died, but only three deaths (9%) were related to EAC. Disease-specific survival at 10 years in node-positive patients was 71%. Conclusions Survival after primary en bloc esophagectomy for submucosal adenocarcinoma was excellent even in node-positive patients. Mortality with esophagectomy was low and far less than the 22% risk of node metastases in patients with submucosal tumor invasion. Esophagectomy should remain the preferred treatment for T1b esophageal adenocarcinoma.

      Abstract: Background This study aimed to examine the prognostic role of Prognostic Nutritional Index (PNI) dynamics in the pre- and postoperative periods for patients with renal cell carcinoma (RCC) who undergo radical nephrectomy (RN). Methods The study analyzed 324 patients with RCC who underwent RN. The overall population was classified into four groups according to four types of pre- to postoperative PNI dynamics as follows: group 1 (low → low PNI), group 2 (low → high PNI), group 3 (high → low PNI), and group 4 (high → high PNI). The level of PNI was calculated using the following formula: 10 × serum albumin level (g/dL) + 0.005 × absolute lymphocyte counts in blood (/mm3). The primary end point was cancer-specific survival (CSS), and the secondary end point was overall survival (OS). Results The patients with higher pre- and postoperative PNI (>45) had better survival outcomes than those with lower pre- and postoperative PNI (≤45). Notably, the patients in group 4 showed the best CSS and OS rates, whereas the patients in group 1 had the worst survival outcomes. Furthermore, PNI dynamics were identified as an independent predictor of CSS and OS outcomes, in addition to pre- and postoperative PNI, tumor size, and pathologic T (pT) stage. The patients with localized RCC (≤pT2) showed significant differences in both CSS and OS estimates, whereas the patients with advanced pT stage (≥pT3) demonstrated a difference only in OS outcomes, according to PNI dynamics. Conclusions This study is the first to provide the independent prognostic importance of dynamics of nutritional status for patients with RCC.

  • Loss of Stromal Antigen 2 (STAG2) Expression in Upper Urinary Tract
           Carcinoma: Differential Prognostic Effect According to the Ki-67
           Proliferating Index

      Abstract: Background Inactivating mutation and consequent expression loss of stromal antigen 2 (STAG2, also known as SA2), a component of the cohesion complex, is one of the most common genetic aberrations in urothelial carcinoma. However, the clinicopathologic or prognostic significance of STAG2 alterations in upper tract urothelial carcinoma (UTUC) is largely unknown. Methods This study immunohistochemically examined the expression of STAG2 in 171 patients with UTUC. The correlations of STAG2 loss with clinicopathologic features and patients’ prognoses were examined. Results Loss of STAG2 expression was observed in 28 cases (16%). Loss of STAG2 was significantly correlated with histological low grade, papillary architecture, noninvasive tumors, absence of concomitant carcinoma in situ, and lower Ki-67 expression. Loss of STAG2 alone was not significantly associated with patients’ prognoses in either the uni- or multivariate analysis. However, STAG2 loss was significantly associated with worse clinical outcome in UTUC with high Ki-67 proliferation indexes, but not in UTUC with low Ki-67 expression. Conclusions Loss of STAG2 was generally associated with less aggressive features in UTUC. However, the STAG2 loss was an ominous sign in the subpopulation with higher Ki-67 proliferation indexes. Examining both STAG2 and Ki-67 status may be useful for identifying aggressive clinical behavior of UTUC.
