Cetuximab with weekly combination chemotherapy (Paclitaxel + Platinum compound) has shown promise, demonstrating comparable response and outcomes with acceptable toxicity in R/M SCCHN patients.
Context:The immune checkpoint inhibitors (ICIs) nivolumab and pembrolizumab have shown dramatic efficacy with low toxicity in international studies of advanced solid cancers. No published Indian experience with ICIs exist other than isolated case reports.Aims:The aim of this study is to evaluate real-world data about the efficacy and toxicity of ICIs in advanced solid cancers among Indian patients who have progressed on one or more prior lines of chemotherapy.Materials and Methods:All patients with advanced solid cancers who received ICIs after the failure of chemotherapy at our center were retrospectively assessed. Information about efficacy and toxicity was collected and analyzed.Results:The present study included 24 patients who had received ICIs for indications including non-small cell lung, bladder, head and neck, gastrointestinal, and unknown primary cancer. Patients had received a median of two prior lines of chemotherapy (range 1–5). Grade III or higher toxicity was seen in 8% of patients. Clinical benefit at 3 months was realized in 33% of evaluable patients. Twenty-six percentages of evaluable patients achieved a response, including one patient who achieved a complete response that is ongoing at 18 months. Median progression-free survival was 3 months, and median overall survival was 8 months at a median follow-up of 10 months. Among patients who achieved clinical benefit, the majority (84%) have an ongoing response at the time of data cutoff.Conclusions:Efficacy and toxicity of ICIs in the Indian population are similar to the experience seen in large international cohorts, and Indian oncologists may feel reassured using these agents in similar settings.
Background Aging is a heterogeneous process, and elderly population is diverse in health status and functional reserve. The present study was undertaken to predict severe chemotherapy toxicity using the Chemotherapy Risk Assessment Scale for High-Age Patients’ (CRASH) score.
Materials and Methods Elderly patients (age ≥65 years) with malignancy, who were planned to be treated with a new course of cytotoxic chemotherapy, were enrolled. The CRASH score was calculated, and patients were stratified into four categories, that is, low (0–3), intermediate (Int)-low (4–6), Int-high (7–9), and high (<9). Patients developing grade 3/4/5 nonhematologic (NH) or grade 4/5 hematologic (H) toxicity were taken as the development of severe toxicity.
Results Of 100 enrolled patients, 64 (64%) were able to complete their prescribed treatment. Forty-four percent of patients (44 patients) of our study cohort experienced grade-4 H or grade 3/4 NH toxicity. The highest score in each category (heme/nonheme/CRASH) predicts nearly 100% toxicity risk. At a critical value of CRASH ≥ 6.5, the sensitivity is calculated as 100%, while specificity is 89.09%. The accuracy of prediction is 93.88%. The median time taken to develop toxicity was 39.5 days.
Conclusion CRASH score utilizes clinical assessment and basic laboratory values. Yet, it accurately predicts severe chemotherapy toxicity above a critical value of 6.5. Based on the above study, the first 30 days are crucial as 45% of patients experienced toxicity in this time frame. With the help of these clinical predictive markers, the care of elderly will be optimized.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
