  • Effects of Pleiotrophin (PTN) on the resistance to paclitaxel in ovarian
           cancer cells

    • Authors: Yunfei Li; Huali Liu, Linlin Ding, Liwei You, Yuqiang Zhang, Xingxing Wang, Xueyuan Lin, Liquan Yang
      Abstract: The pathogenesis of an ovarian disease is connected with PTN and its receptor protein tyrosine phosphatase receptor Z1 (PTPRZ1). Paclitaxel is the first-line drug for the therapy of ovarian cancer. With the increment of paclitaxel chemotherapy, paclitaxel obstruction happens in the late phase of therapy frequently. By treating A2780 and SKOV-3 cells with PTN, we found the development of the two cell lines was enhanced. Different concentrations of PTN were added to A2780 and SKOV-3 cells treated with paclitaxel and the results of MTT showed that the inhibitory effect of paclitaxel on these two cell lines was weakened. The results of apoptosis assays showed that PTN could slow down the rate of apoptosis and its concentration dependence in both cell lines. To further investigate the impact of PTN on the paclitaxel responsiveness of ovarian malignant growth cells, A2780 and SKOV-3 cells were transfected with sh-PTN-1, sh-PTN-2 and sh-NC plasmids. The results of PCR and Western Blot showed that both RNA-interfering plasmids could inhibit PTN in A2780 and SKOV-3 cells. The results of MTT showed that the inhibitory effect of paclitaxel on cells transfected with sh-PTN-1 expanded compared with the benchmark group. Apoptosis assays showed that the complete apoptosis pace of A2780 and SKOV-3 cells with sh-PTN-1 plasmid induced by paclitaxel was accelerated obviously compared with the benchmark group. To summarize, the results suggested that PTN could enhance the resistance to paclitaxel in ovarian cancer cells, which provides a groundwork for studying on drug resistance of cancer cells to paclitaxel and a new perspective for ovarian cancer therapy.

  • Mammographic correlation with molecular subtypes of breast carcinoma

    • Authors: Kundana Rayamajhi; Richa Bansal, Bharat Aggarwal
      Abstract: Aim: To determine the correlation between mammographic features of breast cancer with molecular subtypes and to calculate the predictive value of these features. Materials and method: This is a retrospective study of breast cancer patients presenting between January 2017 and December 2021, who underwent mammography of the breast followed by true cut biopsy and immunohistochemical staining of the tissue sample. Breast carcinoma patients without preoperative mammograms, those unable to undergo histopathological and IHC examinations and h/o prior cancer treatment were excluded. On mammography, size, shape, margins, density, the presence or absence of suspicious calcifications and associated features were noted. Results: Irregular-shaped tumors with spiculated margins were likely to be luminal A/B subtypes of breast cancer. Tumors with a round or oval shape with circumscribed margins were highly suggestive of Triple negative breast cancer. Tumors with suspicious calcifications were likely to be HER2 enriched. Conclusion: Mammographic features such as irregular or round shape, circumscribed or noncircumscribed margins and suspicious calcifications are strongly correlated in predicting the molecular subtypes of breast cancer and thus may further expand the role of conventional breast imaging.

  • Radiation-induced salivary gland damage/dysfunction in head and neck
           cancer: Nano-bioengineering strategies and artificial intelligence for
           prevention, therapy and reparation

    • Authors: Ziyad S Haidar
      Abstract: Saliva is produced by and secreted from salivary glands. It is an extra-cellular fluid, 98% water, plus electrolytes, mucus, white blood cells, epithelial cells, enzymes, and anti-microbial agents. Saliva serves a critical role in the maintenance of oral, dental, and general health and well-being. Hence, alteration(s) in the amount/quantity and/or quality of secreted saliva may induce the development of several oro-dental variations, thereby the negatively-impacting overall quality of life. Diverse factors may affect the process of saliva production and quantity/quality of secretion, including medications, systemic or local pathologies and/or reversible/irreversible damage. Herein, chemo- and/or radio-therapy, particularly, in cases of head and neck cancer, for example, are well-documented to induce serious damage and dysfunction to the radio-sensitive salivary gland tissue, resulting in hypo-salivation, xerostomia (dry mouth) as well as numerous other adverse Intra-/extra-oral, medical and quality-of-life issues. Indeed, radio-therapy inevitably causes damage to the normal head and neck tissues including nerve structures (brain stem, spinal cord, and brachial plexus), mucous membranes, and swallowing muscles. Current commercially-available remedies as well as therapeutic interventions provide only temporary symptom relief, hence, do not address irreversible glandular damage. Further, despite salivary gland-sparing techniques and modified dosing strategies, long-term hypo-function remains a significant problem. Although a single governing mechanism of radiation-induced salivary gland tissue damage and dysfunction has not been yet elucidated, the potential for synergy in radio-protection (mainly, and possibly -reparation) via a combinatorial approach of mechanistically distinct strategies, has been suggested and explored over the years. This is, undoubtfully, in parallel to the ongoing efforts in improving the precision, safety, delivery, and efficacy of clinical radiotherapy protocols/outcomes, and in designing, developing, evaluating and optimizing (for translation) new artificial intelligence, technological and bio-pharmaceutical alternatives, topics covered in this review.

  • Renal neoplasms and computed tomography

    • Authors: Hajra Idrees; MBBS, Raza Zarrar, MBBS, MD, Bilal Mujtaba, MD
      Abstract: Introduction: In recent years the increased utilization of imaging modalities has led to an accelerated diagnosis of renal masses. Initial diagnoses and staging are commonly done with the abdominal Computed Tomography (CT). This study evaluates the various aspects to consider when utilizing CT scan for the diagnosis of renal masses.Discussion: CT scan is the most important imaging modality to evaluate renal neoplasms. Postcontrast acquisitions can be tailored according to the indication for the study. This alongside various techniques, imaging modalities and classification systems may help differentiate the malignant Renal Cell Carcinoma, from benign or metastatic lesions, lymphomas or renal pseudotumor. Finally CT can also be utilized alongside other tools for staging the tumor. Conclusion: Certain CT imaging features are pertinent to evaluate the malignancy potential of renal lesions. However the CT alone may be inconclusive in diagnosing the majority of renal neoplasms, excluding AML with macroscopic fat. Hence it is recommended that the CT aid additional imaging modalities and tools to reach an accurate diagnosis.

  • The effects of boric acid and disodium pentaborate dechydrate in
           metastatic prostate cancer cells

    • Authors: Merve Tütüncü; Selen Kum Özşengezer, Tuğba Karakayali, Zekiye S Altun
      Abstract: Boron and their derived molecules have prevention or treatment potential against prostate cancer. In this study, we aim to investigate the effects of Boric acid (BA) and Disodium Pentaborate Dechydrate (DPD) in metastatic prostate cancer cells such as DU-145 which is brain metastatic prostate cancer, and PC3 which is bone metastatic prostate cancer.Metastatic human prostate cancer cell lines, PC-3 and DU-145, were used to show whether inhibition effects of BA and DPD on prostate cancer cells in this study. BA and DPD were applied for 24 hours to the cells. Cell viability determination was performed using WST-1 assay. Apoptotic cell death was evaluated with Annexin-V/PI flow cytometric analysis and caspase-3 expression immunohistochemically. A wound healing assay was also used to measure cancer cell migration after exposure to BA and DPD.Applying BA and DPD made inhibition of cell proliferation in both BA (1 mM) and DPD (7 mM) at 24 h. The results of Annexin-V/PI showed that DPD induced higher levels of apoptosis than BA in both prostate cancer cells. Caspase-3 expressions were also higher than BA with DPD in both metastatic prostate cancer cells. We evaluated cell migration using a wound healing assay and the result showed that cell migration was inhibited with BA and DPD in both cells. Both BA and DPD inhibited the cell viability of metastatic prostate cancer cells. Apoptotic cell death with applying DPP had a higher rate than BA treatment. Moreover, BA and DPD inhibited cell migration in both cells when we compared them with control. This study’s results showed that BA and DPD of boron derivates significantly induced cells to apoptosis and the migration was inhibited by the derived form of boron in metastatic prostate cancer cells.

  • The value of bone scans to predict survival time in patients with
           diagnosed prostate cancer: single-center retrospective study

    • Authors: Elif Marangoz; Doğangün Yüksel, Olga Yaylalı, Saadettin Yılmaz Eskiçorapçı, Nilay Şen, Hülya Aybek, Fatma Suna Kıraç
      Abstract: Objective: In this study, we investigated the significance of the bone scan results as a prognostic factor to predict survival by comparing age, serum PSA level, and Gleason score. Methods: Medical records of 313 patients were retrospectively examined. 265 patients of 313 were included in the study. Results: 202 (76%) patients of 265 were still alive and 63 (24%) patients of 265 were dead because of prostate cancer. Patients’ mean estimated survival times for those with, without, and suspected bone metastases were 47.4 ± 5.4 months, 159.1 ± 8.6 months, and 71.1 ± 14.4 months, respectively (p = 0.0001). While the mean estimated survival time of < 70 years patients old was 137.1 ± 9.4 months, the mean estimated survival time of ≥ 70 years old patients was 78.2 ± 5.0 (p = 0.031). 243 patients with known PSA values, of those whose PSA levels were < 10 ng/ml, between 10-20 ng/ml, between > 20-50 ng/ml, and > 50 ng/ml, the estimated mean survival time was 106.9 ± 4.2 months, 118.1 ± 14.8 months, 87.6 ± 7.4 months and 51.7 ± 6.2 month, respectively and a significant difference was determined (p = 0.0001). For patients whose Gleason scores were < 7, 7,and >7, the mean estimated survival time was 167.5 ± 10.8 months), 86.8 ± 5.5 months, and 61.0 ± 5.4 months, respectively, and a significant difference was determined (p = 0.0001). Conclusion: We identified that the estimated mean survival time of the patients who had bone metastases, had a high level of PSA, had a high level of Gleason score, and were older than 70 years old was shorter than other groups. We concluded the most important prognostic factor affecting survival time independently was the finding of metastasis detected in bone scintigraphy.

  • Squamous cell carcinoma in a retrorectal cystic hamartoma

    • Authors: Ana Teijo Quintáns; José Ignacio Martín Valadés, Cristina Garrán del Río, Irene López Rojo, Oscar Alonso Casado
      Abstract: Retrorectal cystic hamartomas (HCR) (“tailgut cyst” in English-language literature) are congenital cystic tumors derived from vestiges of the hindgut. Its incidence is low, being more frequent in adult women. They are variable in size, uni or multiloculated. They can be lined with several types of epithelia (squamous, transitional, mucinous,...) in a same cyst and can contain mucus. Lesions usually present during adulthood due to pain, discomfort, rectal bleeding, infection, or malignant transformation. The incidence of malignancy is low, being adenocarcinoma and neuroendocrine the most frequent tumors associated to HCR. We present a case of HCR associated with squamous cell carcinoma and discuss aspects of the treatment.
