Background: The incidence of esophagus carcinoma is raising and it is the 6th leading cause of mortality. The objective of this study is to determine pathological response rate in patients who achieve clinical response after neo-adjuvant concurrent chemoradiotherapy in locally advanced esophageal cancer presented at a single tertiary care centre in Karachi. Patients and methods: It was a longitudinal study conducted at the Department of Oncology of Jinnah Postgraduate Medical College from May 2017 to July 2018. Thirty five patients with locally advanced carcinoma involving lower and middle esophagus had concurrent chemoradiotherapy. Induction of concurrent chemoradiotherapy with radiations in which carboplatin and paclitaxel was given weekly. After 6 weeks at the end of irradiation, the clinical response was assessed on CT scan. All patients who had achieved stable, partial and complete clinical response after completion of concurrent chemoradiotherapy (CCRT) underwent surgery within 6-8 weeks. After surgery, pathologist evaluated resected specimen and staging was done on the basis of residual tumor. To grade the response to therapy, the degree of histomorphologic regression classified into four categories as Pathological complete response (pCR), pathological partial response, stable disease as no pathological response and progression of disease. Statistical analysis was performed using SPSS version 23. Chi-square test was applied to assess association between effect modifiers and complete pathological response.  Results: Total of 35 patients were included in the study. Mean age of the patients was 42.42±14.16 years. There was female preponderance (57.4%) with male to female ratio of 17:18. Eleven patients (31%) achieved complete clinical response and 2 patients (6%) had stable disease. After surgery, complete pathological response was observed in 21 (60%) patients. However, 10 (28.6%) patients achieved partial pathological response, 1 (2.9%) patient had stable disease and 3 (8.6%) patients showed progression of disease. Conclusion: The achievement of complete pathological response was comparatively higher than partial response among locally advanced EC patients who had neoadjuvant CCRT followed by surgery.

202 Background: Neoadjuvant chemotherapy with or without radiotherapy are the common treatments for locally advanced squamous-cell esophageal cancer(ESCC). There is no sufficient data to choose between these two effective therapies. The aim of our retrospective study was to compare the clinical efficacy between these two strategies of complete pathological response (pCR), postoperative morbidity, mortality, and overall and disease-free survival in patients with locally advanced ESCC. Methods: Patients with stage T2-4N0-1M0 squamous-cell esophageal cancer at our institution were recruited, including patients who underwent NCRT (1 cycle of cisplatin and 5-fluorouracil with concurrent radiotherapy) or NCT (2 cycles of cisplatin and 5-fluorouracil only ) before esophagectomy. Results: From January 2009 to October 2015, a total of 177 patients were analyzed, with 72 received NCRT and the remaining 105 received NCT. The pathological complete response (pCR) rate was 22.2% (n = 16) in NCRT group and 9.5% (n = 10) in NCT group ( P= 0.019). The postoperative mortality was 1.4% in NCRT group, versus 4.8% in NCT group. The postoperative morbidity was 20.8% in NCRT group, versus 27.6% in NCT group. There was no significant difference in recurrence between the two groups ( P= 0.397). 1-,2-,3-year overall survival rates in NCRT and NCT group were 87%, 74%, 51% and 81%, 64%, 51%, respectively ( P= 0.527), and 1-,2-,3-year DFS rates were 77%, 54%, 50% and 65%, 54%, 46%, respectively( P= 0.379). Conclusions: For patients with locally advanced squamous-cell esophageal cancer, the addition of radiotherapy to neoadjuvant chemotherapy may result in higher complete pathological response with acceptable postoperative mortality and morbidity, while the long-term survival benefit is not significant.

Abstract Background This retrospective study was to assess and compare the toxicity and efficacy of concurrent chemoradiotherapy (CCRT) with S-1 or docetaxel and cisplatin in patients with locally advanced esophageal squamous cell carcinoma (ESCC). Methods Patients with locally advanced ESCC who received CCRT with S-1 (70 mg/m2 twice daily on days 1–14, every 3 weeks for 2 cycles, S-1 group) or docetaxel (25 mg/m2) and cisplatin (25 mg/m2) on day 1 weekly (DP group) between 2014 and 2016 were retrospectively analyzed. Radiotherapy was delivered in 1.8–2.0 Gy per fraction to a total dose of 50–60 Gy. Treatment-related toxicities (Common Terminology Criteria for Adverse Events version 4.0), response rate, and survival outcomes were compared between groups. Results A total of 175 patients were included in this study (72 in the S-1 group and 103 in the DP group). Baseline characteristics were well balanced between the two groups. The incidence of grade 3–4 adverse events were significantly lower in the S-1 group than that of the DP group (22.2% vs. 45.6%, p = 0.002). In the DP group, elderly patients (> 60 years) had a significantly higher rate of grade 3–4 adverse events than younger patients (58.1% vs. 31.3%, p = 0.01). The objective overall response rate (complete response + partial response) was 68.1% in the S-1 group, and 73.8% the DP group (p = 0.497). The 3-year overall survival was 34.7% in the S-1 group, and 38.8% in the DP group (p = 0.422). The 3-year progression free survival in the DP group was higher than that in the S-1 group but without significant difference (33.0% vs. 25.0%, p = 0.275). Conclusion CCRT with S-1 is not inferior to CCRT with docetaxel and cisplatin and is better tolerated in in elderly patients with locally advanced ESCC.

Abstract Background Homologous recombination deficiency is a marker of response to poly(ADP-ribose) polymerase inhibitors in different cancer types including ovary, prostate, and pancreatic cancer. To date, no report about poly(ADP-ribose) polymerase inhibitors has been published on cervical cancer. Case presentation Here we present the case of a patient with cervical cancer treated in this setting. A 49-year-old woman diagnosed with International Federation of Obstetricians and Gynecologists stage 2018 IIIC2 locally advanced undifferentiated cervical cancer received first-line chemoradiotherapy followed by carboplatin, paclitaxel, and bevacizumab with partial response. Because of a family history of cancers, the patient was tested and found positive for a pathogenic BRCA1 germline and somatic mutation, which motivated bevacizumab plus olaparib maintenance treatment. A simple hysterectomy was performed after 2 years stable disease; pathological report showed complete pathological response, and 12 months follow-up showed no recurrence. Conclusion Poly(ADP-ribose) polymerase inhibitors could be an alternative maintenance treatment for patients with persistent advanced cervical cancer previously treated with platinum, especially when familial history of cancers is reported. Clinical trials using poly(ADP-ribose) polymerase inhibitors for advanced cervical cancer are warranted.
