      Abstract: Background Melanoma metastatic to the large bowel (colon, rectum, and anus) is rarely diagnosed, with more than 95% of large bowel metastases identified post-mortem. The incidence, natural history, and survival rates of patients with large bowel melanoma metastases are poorly documented in the literature. Objective This study aimed to identify the incidence, clinical characteristics, and survival of patients with large bowel melanoma metastases. Methods A review was undertaken of all patients with melanoma treated over a 50-year period (1964–2014) at a tertiary referral center. Cases selected for study were those diagnosed with melanoma metastases in the colon, rectum, and anus. Primary colorectal and anal melanomas were excluded. Data were retrieved relating to patient demographics, clinical features, and survival. Results Of 38,279 patients with primary melanoma, 106 patients (0.3%, mean age 51.0 years [standard deviation 16.3], 64 males) developed large bowel metastases. The median interval between diagnosis of primary melanoma and large bowel metastasis was 62.8 months (range 1–476). The most common symptom was rectal bleeding (29.2%), and the large bowel was the sole site of metastasis in 47.2% of patients. Median survival from diagnosis of large bowel metastasis was 31.7 months (range 1–315), and overall survival at 1, 2, and 5 years was 68.1, 45.9, and 26.5%, respectively. Conclusion Our study provides insights into melanoma metastatic to the colon, rectum, and anus, which had an incidence of 0.3%. There are potentially long intervals between diagnosis of primary melanoma and large bowel metastasis. The most common symptom was rectal bleeding, although some patients were asymptomatic.

      Abstract: Background To evaluate short- and long-term results after curative surgery for a retroperitoneal sarcoma (RPS) in elderly patients. Methods We retrospectively analyzed data of all patients operated in our single, tertiary care center for a nonmetastatic RPS and identified patients aged 70 years and older. Results Among 296 patients with an RPS treated between 1994 and 2015, 60 (20%) were aged 70 years and older (median age 74 years; range 70–85). The median tumor size was 24 cm (range 6–46). Forty-six patients (77%) had mass-related symptoms at the time of diagnosis. The most frequent histological subtypes were de-differentiated liposarcoma (53%, n = 32) and well-differentiated liposarcoma (35%, n = 21). Twenty-two patients (37%) had perioperative radiotherapy and/or chemotherapy. Fifty-eight patients (97%) had macroscopically complete resection. The postoperative mortality was 8% and severe morbidity (Dindo/Clavien ≥ 3) was 32%. A reoperation was required for ten patients (17%). After a median follow-up of 20 months (range 1–121), the 5-year overall survival (OS) rate was 90% (95% confidence interval [CI] 79–100%), and median OS was not reached. The cancer-specific death rate was 88%. No prognostic factor for disease-specific survival was detected. The 5-year disease-free survival (DFS) rate was 52% (95% CI 33–84%) and 5-year locoregional recurrence-free survival rate was 52% (95% CI 33–84%). Median DFS was 94 months (95% CI 35–NA). Reoperation after inappropriate surgery and postoperative morbidity were independent predictive factors of locoregional relapse. No predictive factors of distant metastasis were found. Conclusions Curative surgery is feasible in selected elderly patients but with higher mortality and morbidity rates than in younger patients. It enables a prolonged survival. Future studies should focus on selection process to minimize postoperative mortality and morbidity.

      Abstract: Background We examined axillary surgery in mastectomy patients with tumor-positive nodes and how the type of axillary surgery impacted use of postmastectomy chest wall radiation therapy (PMRT). Methods Using the National Cancer Data Base, we selected patients with AJCC cT1/T2c N0 breast cancer with one to three tumor-positive lymph nodes treated between 2013 and 2014. Type of axillary surgery was analyzed using the FORDS scope of regional lymph node surgery variable. Multivariable logistic regression modeling was used to identify independent predictors associated with SNB alone and the use of PMRT. Results Of 8089 patients, 2482 (30.7%) underwent SNB alone, 1339 (16.6%) underwent axillary dissection (ALND) alone, and 4268 (52.7%) underwent SNB followed by ALND. Fifty-seven percent of patients with micrometastases underwent SNB alone compared with 22.6% of patients with macrometastases. Independent predictors of SNB alone for patients with micrometastases were African American race, number of nodes positive, and PMRT. For patients with macrometastases, age, facility type and location, and PMRT were independent predictors for SNB alone. Of 2449 patients who underwent SNB alone, 1538 (62.8%) had no PMRT, 261 (10.7%) had PMRT alone, and 650 (26.5%) had PMRT with regional nodal irradiation. Patients undergoing SNB alone were 1.70 times [96% confidence interval (CI) 1.45–2.00] more likely to undergo PMRT than upfront ALND and 1.51 times (96% CI 1.34–1.71) more likely than SNB followed by ALND. Conclusions Surgeons are omitting completion ALND in a third of early-stage, node-positive mastectomy patients. SNB alone patients are more likely to undergo PMRT than patients undergoing ALND.

      Abstract: Background Current guidelines recommend counseling on risk-reduction strategies, including lifestyle modification, endocrine therapy, and bilateral mastectomy, for patients with classic-type lobular carcinoma in situ (LCIS) detected on core biopsy or surgical excision. Importantly, current diagnosis and treatment guidelines for classic-type LCIS do not include unilateral mastectomy for primary treatment or risk reduction. Prior studies reporting national practice patterns suggest increasing use of mastectomy for management of LCIS, with considerable variation by geographic region. However, these studies did not distinguish between uni- and bilateral mastectomies. This study aimed to investigate national practice patterns and factors associated with unilateral mastectomy. Methods The study used the National Cancer Database to identify women with a diagnosis of LCIS from 2004 to 2013. Descriptive statistics were used to describe surgical treatment, and multinomial logistic regression was used to identify temporal, patient, and facility-level factors associated with receipt of uni- and bilateral mastectomy. Results The study identified 30,105 women with LCIS. Of these woman, 5.4% received no surgery, 84.8% had surgical excision, 4% underwent unilateral mastectomy, and 5.1% underwent bilateral mastectomy. Adjusted analysis showed that young age, white race, insurance coverage, greater comorbidity, and geographic region (p < 0.001) were associated with receipt of both uni- and bilateral mastectomy. Additionally, more recent year of diagnosis was associated with receipt of bilateral mastectomy. Unilateral mastectomy rates within geographic regions ranged from 2.7% in New England to 8% in the South. Conclusions Nearly as many patients underwent unilateral (4%) as bilateral mastectomy (5.1%), representing inappropriate care. These findings highlight an opportunity to reduce unnecessary care through improved provider and patient education regarding optimal management of LCIS.

  • Evaluation of the Relationship Between Flap Tension and Tissue Perfusion
           in Implant-Based Breast Reconstruction Using Laser-Assisted Indocyanine

      Abstract: Background For implant-based breast reconstruction, inadequate tissue perfusion may cause devastating complications. Tissue tension by inadequate implant volume may reduce tissue perfusion by stretching and collapsing the capillaries. The SPY system is used to perform intraoperative fluorescence angiography with indocyanine green to assess visually the blood flow and evaluate tissue perfusion. However, there is no report yet about how mastectomy flap perfusion changes with the expander-filling volume. Therefore, to analyse the changes of tissue perfusion of the mastectomy flap according to the tension level, we used the SPY system and adjusted the filling volume of the tissue expander to change the tension on the skin flap. Methods Ten breasts of ten patients who underwent immediate two-stage, implant-based breast reconstructions were included. The expander-filling volume just before mastectomy flap blanching was set as 100%. Based on this, the expander-filling volume was reduced to 50% and increased to 150%. Ingress and egress rates were evaluated using the SPY system at each condition and analysed by a linear mixed model using least square means. Results The mean ingression rates were 138, 100, and 65%, and the mean egression rates were 145, 100, and 66% at 50, 100, and 150% inflation, respectively. Conclusions It was objectively proven that tissue perfusion deteriorates as the tension applied on the flap increases. On the basis of this finding, we can control the amount of inflation volume of the expander or remove the skin in the pre-ischaemic condition to reduce complications of implant-based breast reconstruction.

  • Neoadjuvant Chemotherapy Use in Breast Cancer is Greatest in Excellent
           Responders: Triple-Negative and HER2+ Subtypes

      Pages: 2241 - 2248
      Abstract: Background While breast cancer has historically been treated with surgery followed by adjuvant chemotherapy (AC) and radiation when indicated, neoadjuvant chemotherapy (NAC) use is thought to be increasing; however, the trends of its use in various biological subtypes have not been evaluated. We sought to evaluate the trend of NAC use over time by biological subtype. Methods We identified all patients with invasive breast cancer who underwent curative intent surgery and were treated with chemotherapy from 2010 to 2015 from the National Cancer Database. An unadjusted analysis of trends in proportions over time was performed using Cochran–Armitage trend tests stratified by hormone receptor (HR) and human epidermal growth factor receptor 2 (HER2) status. Results Of 315,264 patients who received chemotherapy, 251,726 (79.8%) received AC and 63,538 (20.2%) received NAC. From 2010 to 2015, significant increases in NAC use were seen in all biologic subtypes (all p < 0.001). The highest proportions and greatest increases in proportions of NAC were seen among triple-negative breast cancers (TNBC; 19.5–33.7%) and HER2+ (HR−/HER2+, 21.5–39.8%; HR+/HER2+, 17.0–33.7%) tumors. HR+/HER2− tumors also had a statistically significant increase in use but this increase was less dramatic (13.0–16.8%) and NAC use in recent years was significantly lower than in other subtypes (p < 0.001). Conclusion Within patients receiving chemotherapy for breast cancer, its receipt in the neoadjuvant setting has been increasing among all biologic subtypes. The highest use of NAC is in TNBC and HER2+ disease, with use in these subgroups being twice as frequent as in HR+/HER2− disease.

      Abstract: Background We characterized the whole transcriptome of circulating tumor cells (CTCs) in stage II–III breast cancer to evaluate correlations with primary tumor biology. Methods CTCs were isolated from peripheral blood (PB) via immunomagnetic enrichment followed by fluorescence-activated cell sorting (IE/FACS). CTCs, PB, and fresh tumors were profiled using RNA-seq. Formalin-fixed, paraffin-embedded (FFPE) tumors were subjected to RNA-seq and NanoString PAM50 assays with risk of recurrence (ROR) scores. Results CTCs were detected in 29/33 (88%) patients. We selected 21 cases to attempt RNA-seq (median number of CTCs = 9). Sixteen CTC samples yielded results that passed quality-control metrics, and these samples had a median of 4,311,255 uniquely mapped reads (less than PB or tumors). Intrinsic subtype predicted by comparing estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) versus PAM50 for FFPE tumors was 85% concordant. However, CTC RNA-seq subtype assessed by the PAM50 classification genes was highly discordant, both with the subtype predicted by ER/PR/HER2 and by PAM50 tumors. Two patients died of metastatic disease, both of whom had high ROR scores and high CTC counts. We identified significant genes, canonical pathways, upstream regulators, and molecular interaction networks comparing CTCs by various clinical factors. We also identified a 75-gene signature with highest expression in CTCs and tumors taken together that was prognostic in The Cancer Genome Atlas and Molecular Taxonomy of Breast Cancer International Consortium datasets. Conclusion It is feasible to use RNA-seq of CTCs in non-metastatic patients to discover novel tumor biology characteristics.

  • Routine Axillary Ultrasound for Patients with T1–T2 Breast Cancer Does
           Not Increase the Rate of Axillary Lymph Node Dissection Based on
           Predictive Modeling
    • Authors: Jennifer Wellington; Thomas Sanders; Charles Mylander; Ashley Alden; Christine Harris; Robert Buras; Lorraine Tafra; Wen Liang; Lacey Stelle; Martin Rosman; Rubie Sue Jackson

      Abstract: Background Since publication of the American College of Surgeons Oncology Group Z0011 trial results, demonstrating that many patients with nonpalpable axillary lymph nodes and one or two positive sentinel nodes do not require axillary lymph node dissection (ALND), preoperative axillary ultrasound (AUS) has become controversial. Clinicians are concerned that AUS may lead to unnecessary ALND. The authors developed an algorithm (Algorithm 1) in which the number of AUS-suspicious nodes and tumor biology direct management. For estrogen receptor-positive (ER+)/human epidermal growth factor receptor 2-negative (HER2–) breast cancer with a single AUS-suspicious node and a positive lymph node needle biopsy (LNNB), sentinel lymph node biopsy (SLNB) is performed with a specimen X-ray documenting retrieval of the clipped node. Other patients with positive LNNB receive neoadjuvant chemotherapy. The authors hypothesized that routine AUS and this algorithm could decrease ALND compared with a strategy of no preoperative AUS. Methods Decision-tree analysis and Monte Carlo simulation were used to assess the expected number of ALNDs under two strategies (routine AUS vs no AUS). Probabilities were drawn from a literature review and an institutional database. The authors assumed nodal pathologic complete response rates as reported in the literature. Four additional algorithms were created to assess whether any other treatment model could decrease the rate of ALND. Results Using the routine AUS and the authors’ algorithm, the predicted ALND rate was 9%, versus 10% for a strategy of no AUS, with overlapping uncertainty intervals. The remaining treatment algorithms showed similar results. Discussion Use of AUS may help to tailor patient care without leading to overutilization of ALND, as long as neoadjuvant chemotherapy is administered when appropriate.

  • Inhibition Mechanism of Acellular Dermal Matrix on Capsule Formation in
           Expander–Implant Breast Reconstruction After Postmastectomy Radiotherapy
    • Authors: Il-Kug Kim; Seong Oh Park; Hak Chang; Ung Sik Jin
      Pages: 2279 - 2287
      Abstract: Background Capsular contracture is one of the most common complications of expander–implant breast reconstruction. Recently, clinical reports have shown that use of an acellular dermal matrix (ADM) to cover breast implants decreases incidence of capsular contracture, but the underlying mechanism is unclear. Here, we examine how ADM reduces capsular formation in expander–implant breast reconstruction and identify cellular and molecular mechanisms of ADM-mediated reduction of capsular contracture in nonirradiated and irradiated patients. Methods Thirty patients who underwent immediate two-stage implant-based breast reconstruction were included; 15 received radiotherapy. While the tissue expander was changed to permanent silicone implant, biopsies of the subpectoral capsule and ADM capsule were performed. Capsule thickness, immunohistochemistry of α-smooth muscle actin (αSMA), vimentin, CD31, F4/80 expression, αSMA and CD31 coexpression, and relative gene expression levels of transforming growth factor (TGF)-β1 and platelet-derived growth factor (PDGF)-B were investigated. Results Irradiated submuscular capsules were thicker than nonirradiated submuscular capsules, but the thickness of ADM capsules did not significantly differ between nonirradiated and irradiated groups. Levels of myofibroblasts, fibroblasts, vascularity, EndoMT, and macrophages were significantly lower in ADM capsules than in submuscular capsules. With the exception of EndoMT, all others were increased in irradiated submuscular capsules compared with nonirradiated submuscular capsule, while none significantly differed between nonirradiated and irradiated ADM capsules. Conclusions Use of ADM reduced myofibroblasts, vascularity, fibroblasts, and EndoMT in capsule tissues. Moreover, ADM use decreased macrophages, a key regulator of tissue fibrosis, as well as TGF-β1 and PDGF-B expression. We hope that these results provide basic concepts important for prevention of capsular contracture.

  • Heterogeneity in Outcomes of Pathologic T1-2N1 Breast Cancer After
           Mastectomy: Looking Beyond Locoregional Failure Rates
    • Authors: Jose G. Bazan; Lonika Majithia; Allison M. Quick; Jessica L. Wobb; Alicia M. Terando; Doreen M. Agnese; William Farrar; Julia R. White
      Pages: 2288 - 2295
      Abstract: Purpose A meta-analysis of 22 randomized trials accrued from 1964 to 1986 demonstrated significantly higher rates of locoregional failure (LRF) and breast-cancer mortality in women with 1–3 positive nodes without postmastectomy radiotherapy (PMRT) after mastectomy (mast.). Recent data demonstrate that PMRT reduces distant metastases (DM) in women with pN1 disease. The challenge today is whether all patients with pathologic T1-2pN1 disease have similar substantial LRF/DM risk that routinely warrants PMRT. Methods We reviewed patients with pT1-2N1 breast cancer treated with mast. ± adjuvant systemic therapy without PMRT from 2000 to 2013. The endpoints were LRF and DM rates, estimated by cumulative incidence method. Results We identified 468 patients with median follow-up of 6.3 years. Most (71%) were estrogen receptor/progesterone receptor + human epidermal growth factor receptor 2 (HER2). There were 269 patients with 1+ node, 140 patients with 2+ nodes, and 59 patients with 3+ nodes. The 6-year LRF/DM rates were 4.1%/8.4%. Patients with 1+, 2+, and 3+ nodes had 6-year LRF of 2.3, 5.1 and 8.9%, respectively (p = 0.13). The 6-year DM rate was higher in patients with 3+ nodes versus 1–2+ nodes: 15.7% versus 7.4% (p = 0.02). Several subgroups had low 6-year LRF and DM rates, including T1/1+ node (0.8%/4.1% LRF/DM) and micrometastases (0%/5.8% LRF/DM). Conclusions Patients with pT1-2pN1 represent a heterogeneous group with a wide range of LRF/DM rates. In particular, patients with pT1 tumors and 1 + LN, and patients with micrometastases, had low event rates. These groups would derive small absolute reductions in LRF and DM with addition of PMRT, underscoring the importance of patient selection for PMRT in pT1-2pN1 breast cancer.

  • Cost Effectiveness of Cytoreductive Surgery and Hyperthermic
           Intraperitoneal Chemotherapy for Management of Colorectal Peritoneal
    • Authors: Z. J. Lee; S. L. Chia; G. Tan; K. C. Soo; C. C. M. Teo
      Pages: 2340 - 2346
      Abstract: Background Peritoneal carcinomatosis from colorectal cancer is a stage 4 disease for which palliative chemotherapy has traditionally been considered the mainstay of treatment. Since the development of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) by Sugarbaker, this combined method treatment has resulted in improved survival outcomes with acceptable morbidity for selected patients with peritoneal carcinomatosis. This study examined the cost effectiveness of CRS and HIPEC compared with palliative chemotherapy for patients with peritoneal carcinomatosis from colorectal cancer within the context of the Singaporean health care system. Methods A retrospective review of patients with peritoneal carcinomatosis from histologically proven colorectal cancer treated at the National Cancer Centre Singapore (NCCS) was conducted. Results The average cost of CRS and HIPEC per patient was S$83,680.26, and the median overall survival period was 47 months. The calculated cost per life year attained for a patient who underwent CRS and HIPEC was S$21,365.19 per life year. In comparison, the average cost of palliative chemotherapy was S$44,478.87, with a median overall survival of 9 months, and the calculated cost per life year attained for a patient in this treatment group was S$59,305.16 per life year. Conclusion The findings show that CRS and HIPEC results in prolonged survival for selected patients with colorectal peritoneal carcinomatosis and a lower cost per life year attained than for the traditionally used palliative chemotherapy. It should logically be the preferred treatment of choice for selected patients with colorectal peritoneal metastasis.

  • Compliance with an Enhanced Recovery After a Surgery Program for Patients
           Undergoing Gastrectomy for Gastric Carcinoma: A Phase 2 Study
    • Authors: Mi Ran Jung; Seong Yeob Ryu; Young Kyu Park; Oh Jeong
      Pages: 2366 - 2373
      Abstract: Background Enhanced recovery after surgery (ERAS) programs have gained widespread acceptance in different fields of major surgery. However, most elements of perioperative care in ERAS are based on practices that originated from colorectal surgery. This study investigated compliance with the main elements of ERAS for patients undergoing gastrectomy for gastric carcinoma. Methods This phase 2 study enrolled 168 patients undergoing elective gastrectomy for gastric carcinoma. An ERAS program consisting of 18 main elements was implemented, and compliance with each element was evaluated (, NCT01653496). Results Distal gastrectomy was performed for 142 patients (84.5%) and total gastrectomy for 26 patients (10.1%). Laparoscopic surgery was performed for 141 patients (86%). The postoperative morbidity rate was 9.5%, and the mortality rate was 0%. The rates of compliance with the 18 main elements of ERAS ranged from 88.1 to 100%. The lowest compliance rate was observed in the restriction of intravenous fluid element (88.1%). Overall, all ERAS elements were successfully applied for 122 patients (72.6%). In the multivariate analysis, the significant factors that adversely affected compliance with ERAS were surgery during the early study period [odds ratio (OR) 0.39; p = 0.038], open surgery (OR 0.15; p <0.001), and postoperative morbidity (OR 0.16; p = 0.003). Conclusions Most elements of ERAS can be successfully applied for patients undergoing gastrectomy for gastric carcinoma. Multimodal collaboration between providers is essential to achieve proper application of ERAS.

      Abstract: Background The optimal treatment strategy for elderly patients with gastric cancer is still controversial. This study aimed to assess the impact of age on short- and long-term outcomes after treatment for primary gastric cancer. Methods From January 2004 to December 2014, a total of 507 patients underwent gastrectomy for gastric adenocarcinoma at two high-volume upper gastrointestinal (GI) centers. The patients were classified into three groups as follows: group A (patients ≤ 69 years old, n = 266), group B (patients 70–79 years old, n = 166), and group C (patients ≥ 80 years old, n = 75). Clinicopathologic characteristics as well as, short- and long-term outcomes were compared between the groups. Results The patients in groups B and C had more comorbidities, whereas the younger subjects (group A) had more advanced tumor stages. Less extensive surgery was performed in the groups B and C. Older patients (age ≥ 70 years) had more postoperative medical complications. Moreover, group C had a higher postoperative mortality rate (8.1%) than group A (1.8%) or group B (1.9%). In the multivariable analysis, age older than 80 years (group C) was a negative independent factor for overall survival (OS) (hazard ratio [HR], 2.36) compared with group A, whereas group B seemed to have a comparable risk (HR, 1.37). Notably, the three groups did not show significant differences in disease-related survival (DRS). Conclusion The data suggest that patients 70–79 years of age show a risk of postoperative death comparable with that of younger subjects. However, patients older than 80 years should be carefully selected for surgical treatment due to the increased risk of postoperative mortality.

  • Comparison of Outcome of Esophagectomy Versus Nonsurgical Treatment for
           Resectable Esophageal Cancer with Clinical Complete Response to
           Neoadjuvant Therapy
    • Authors: Yu Ohkura; Junichi Shindoh; Masaki Ueno; Toshiro Iizuka; Harushi Udagawa
      Pages: 2428 - 2433
      Abstract: Background Treatment for patients who have achieved clinical complete response (cCR) after neoadjuvant therapy has not been established, and there is no consensus regarding the indications for either esophagectomy or nonsurgical treatment. Methods Among 1,545 patients with esophageal cancer at Toranomon Hospital between January 2006 and August 2017, 39 who achieved cCR after neoadjuvant treatment were divided into two groups according to treatment: esophagectomy group (n = 18) and nonsurgical treatment group (n = 21) for comparison. Results No significant intergroup difference was observed in baseline characteristics. Pathological complete response was confirmed in 13 (72.2%) of the 18 patients who underwent esophagectomy, whereas residual tumor was detected at the location of primary tumor in 2 (11.1%) patients, and lymph node metastasis was found in 3 (16.7%) patients. Recurrence-free survival (RFS) was significantly longer in the esophagectomy group than in the nonsurgical group (p = 0.002). Disease-specific survival (DSS) was significantly longer in the esophagectomy group (p = 0.007). However, no significant intergroup difference was observed in overall survival estimated based on all deaths, including respiratory failure and aspiration pneumonia (p = 0.451). Conclusions With improved diagnostic accuracy, nonsurgical treatment can be an option for patients estimated as cCR after treatment administered in a neoadjuvant setting. However, surgical resection is considered more appropriate because of residual tumor in some patients with cCR and because of superior DSS and RFS following esophagectomy compared with nonsurgical treatment. Future studies must focus on ameliorating late postoperative complications, such as respiratory failure and aspiration pneumonia.
