Objective: Triple negative breast cancer is an aggressive variant of breast cancer; it forms about 15% of breast cancer cases. It lacks the responsiveness to hormonal and targeted therapies. Anthracyclines remain the treatment option for these patients. Anthracyclines are cardiotoxic, so predicting sensitivity of response by biological predictors may have a role in selecting suitable candidates for these drugs. Material and methods: This study included 50 TNBC cases, from National Cancer Institute, Cairo University(NCI-CU), Egypt, who underwent surgery and received adjuvant chemotherapy. Archived blocks were obtained and immunostaining for Ki-67 LI and Fluorescent In situ Hybridization (FISH) technique to assess TOP2A gene copy number and chromosome 17CEP status were done. Analysis of association between TOP2A alterations and CEP17 polysomy as well as Ki-67 LI with other clinicopathological parameters was done. Associations between the biological markers and event free survival (EFS) and overall survival (OS), were also performed. Results: TOP2A alteration was seen in 9/50 cases (5 amplified and 4 deleted). CEP17 Polysomy was detected in 14% of cases. Most of patients (80%) showed Ki-67 LI ≥20%. There was a significant association between TOP2A gene and CEP17 status. Outcome was better with abnormal TOP2A gene status and CEP17 polysomy, radiotherapy and combined anthracyclines and taxanes in the adjuvant setting, however P-values were not significant. Conclusion: TOP2A gene alterations and CEP17 polysomy may have prognostic and predictive role in TNBC treated with adjuvant Anthracyclines.

Background Gastric adenocarcinoma is one of the most aggressive forms of cancer. Despite marked advancements in radiological techniques, peritoneal deposits are still only discovered during laparotomies in a significant number of cases. The role of surgery in the management of metastatic gastric cancer is very limited, reducing the value of conducting laparotomies. In addition, conducting laparoscopies for the purposes of properly staging every case of gastric cancer is difficult, especially in healthcare systems with limited resources. It is thus crucial to investigate all possible predictors of peritoneal metastasis of gastric cancer, with the aim of reserving the use of laparoscopies to cases known to have high incidences of peritoneal metastasis despite negative radiological results. Patients and methods This is a case control study that included all cases of gastric adenocarcinoma that had presented to the National Cancer Institute–Cairo University between January 2018 and December 2019. The ‘cases’ group encompassed all gastric adenocarcinoma patients who were found to have peritoneal metastasis, whilst the ‘control’ group included those patients who were apparently metastasis-free. Comparisons were made between the two groups in terms of demographics, tumor characteristics, and results of laboratory tumor marker investigations. Results Patients with peritoneal metastasis were statistically significantly younger than those who had no apparent metastasis (mean ± SD 51.4 ± 12.5 and 56.2 ± 12.6 respectively; P = 0.020). Significant associations were found between a finding of peritoneal metastasis and (i) a middle tumor site (P = 0.002); (ii) tumor thickening morphology (P < 0.001); (iii) undifferentiated histopathology (P = 0.040); (iv) tumor grade III (P < 0.001); (v) lower lymphocyte counts of < 1.9/ml (P = 0.030); and (vi) high levels of CA 19-9 of > 37 units/ml (P = 0.032). Conclusion Tumor pathological criteria, including tumor site, degree of differentiation, shape, and grading, as well as laboratory findings of low lymphocytic counts and high levels of CA 19-9 appear to be reliable predictors of the presence of peritoneal metastasis from a gastric adenocarcinoma.

Background: Due to late detection, a low percentage of resectable malignancies, and resistance to systemic therapy, pancreatic ductal adenocarcinoma (PDAC) has the poorest outcome of all pancreatic cancers. The basis of contemporary multimodal therapies aimed at long-term survival is complete lesion excision. Postoperative complications are common consequences following pancreaticoduodenectomy (PD). Objective: To investigate the outcome and factors contributing to the 1 st year survival after Whipple's procedure for pancreatic ductal adenocarcinoma. Patients and Methods: Between January 2020 and December 2021, all patients identified with pancreatic ductal adenocarcinoma (61 individuals) who had Whipple's surgery in the surgical department at the National Cancer Institute were included in this retrospective cohort analysis. Results: Wound infection (49.2%), followed by pancreatic leak (41.7%) were the most prevalent complications among the 61 patients who received PD. The 1 st year survival rate was 77% (47/61). In multivariate assessment postoperative pancreatic fistula and adjuvant treatment were independent predictors of 1 st year survival. Conclusion: In multimodally managed patients following curative PDAC surgery, individuals who acquired a postoperative pancreatic fistula and did not get adjuvant therapy had greater 1st year death rates.
