Background and aims COVID-19 has impacted healthcare system worldwide including cancer case. Aim of this study was to describe the experience of lockdown on cancer care concerning patient's visit and reception of treatment in western India. Methods This is a retrospective observational study conducted in patients with cancer attending a tertiary care center pre-lockdown and during lockdown (from January to May 2020). Data related to demographic parameters, type of tumor, type of treatment received and functional status of patients were retrieved from hospital medical records of patients. Results Of the 5258 patients included, 4363 visited hospital pre-lockdown (median age, 50 years) and 895 visited during the lockdown period (median age, 47 years). A total of 1168 and 106 patients visiting hospital before and during lockdown, respectively, had comorbidities. Breast cancer (25.6% and 29.7%), head and neck cancer (21.3% and 16.9%) were the most common type of solid tumors; leukemia (58.0% and 73.0%), lymphoma (18.8% and 13.5%) and multiple myeloma (18.6% and 12.2%) were the most common type of hematological malignancies observed in patients visiting pre-lockdown and during lockdown, respectively. Chemotherapy was most commonly received treatment (pre-lockdown, 71.8%; during lockdown, 45.9%). Other therapies reported includes supportive/palliative, targeted, hormonal, and immunotherapy. The majority of patients who visited the hospital pre-lockdown (68.4%) and during lockdown (62.8%) had 0 or 1 Eastern Cooperative Oncology Group (ECOG) score. Conclusion Overall observations highlight a substantial impact of an imposed nationwide lockdown during COVID-19 pandemic on cancer care of patients in terms of reduced patient visits and number of treatments received.

Background Immunotherapy is a proven therapeutic option in recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC) after platinum therapy. At present, there are no published Indian data regarding administration of nivolumab in this setting. Aim The aim of this study is to retrospectively evaluate the efficacy and toxicity of nivolumab in R/M HNSCC among Indian patients who progressed after one or more lines of chemotherapy, including platinum agents. Methods All patients of R/M HNSCC who received nivolumab between 2/6/2018 to 31/3/2020 were assessed retrospectively for the efficacy and toxicity of nivolumab therapy. Statistical Analysis All the data analysis was performed using IBM SPSS Statistics for Windows, version 25 (IBM Corp., Armonk, N.Y., USA). Descriptive analysis was performed to obtain baseline characteristic of the study sample. Survival analysis was done using the Kaplan–Meier method. Results Nivolumab therapy was tolerated well, with no new safety concerns, except one (8.3%) patient experienced grade ¾ toxicity (gastrointestinal). The clinical benefit rate (CBR) was found to be 66.7%. The median progression-free survival (PFS) was 3 months (95% CI; 2.093–3.907), and median overall survival (OS) was 8 months (95% CI; 3.731–12.269) from the date of first dose of nivolumab. Conclusions In our study, efficacy and toxicity were comparable with international data with no new safety concerns. Nivolumab emerged as an astonishing treatment option with tolerable toxicity profile in patients with R/M HNSCC postplatinum therapy, although limited treatment options are available at present.
