Olanzapine is an effective antiemetic agent but it results in substantial daytime somnolence when administered at the standard dose. Our aim was to compare the efficacy of low-dose versus standard-dose olanzapine after highly emetogenic chemotherapy in patients with solid tumours. This was a single-centre, open-label, non-inferiority, randomised, controlled, phase 3 trial done in a tertiary care referral centre in India (Tata Memorial Centre, Homi Bhabha National Institute, Mumbai). Patients aged 13–75 years with an Eastern Cooperative Oncology Group performance status of 0–2, who were receiving doxorubicin–cyclophosphamide or high-dose cisplatin for a solid tumour were eligible. Patients were randomly assigned (1:1), with block randomisation (block sizes of 2 or 4) and stratified by sex, age (≥55 or <55 years), and chemotherapy regimen, to receive low-dose (2·5 mg) oral olanzapine or standard-dose (10·0 mg) oral olanzapine daily for 4 days, in combination with a triple antiemetic regimen. Study staff were masked to treatment allocation but patients were aware of their group assignment. The primary endpoint was complete control, defined as no emetic episodes, no rescue medications, and no or mild nausea in the overall phase (0–120 hours), assessed in the modified intention-to-treat (mITT) population (ie, all eligible patients who received protocol-specified treatment, excluding those who had eligibility violations and who withdrew consent after randomisation). Daytime somnolence was the safety endpoint of interest. Non-inferiority was shown if the upper limit of the one-sided 95% CI for the difference in the complete control proportions between the treatment groups excluded the non-inferiority margin of 10%. This study is registered with the Clinical Trial Registry India, CTRI/2021/01/030233, is closed to accrual, and this is the final data analysis. Between Feb 9, 2021, and May 30, 2023, 356 patients were pre-screened for eligibility, of whom 275 patients were enrolled and randomly assigned (134 to the 2·5 mg olanzapine group and 141 to the 10·0 mg olanzapine group). 267 patients (132 in the 2·5 mg group and 135 in the 10·0 mg group) were included in the mITT population, of whom 252 (94%) were female, 15 (6%) were male, and 242 (91%) had breast cancer. 59 (45%) of 132 patients in the 2·5 mg olanzapine group had complete control in the overall phase versus 59 (44%) of 135 in the 10·0 mg olanzapine group (difference –1·0% [one-sided 95% CI –100·0 to 9·0]; p=0·87). In the overall phase, there were significantly fewer patients in the 2·5 mg olanzapine group than in the 10·0 mg olanzapine group with daytime somnolence of any grade (86 [65%] of 132 vs 121 [90%] of 135; p<0·0001) and of severe grade on day 1 (six]5%] vs 54 [40%]; p<0·0001). Our findings suggest that olanzapine 2·5 mg is non-inferior to 10·0 mg in antiemetic efficacy and results in reduced occurrence of daytime somnolence among patients receiving highly emetic chemotherapy and should be considered as a new standard of care.

ImportanceThe Cancer Aging Research Group (CARG) toxicity score is used to assess toxicity risk in geriatric patients receiving chemotherapy.ObjectiveThe primary aim was to validate the CARG score in geriatric patients treated with curative intent chemotherapy in predicting grade 3–5 toxicities.DesignThis was a longitudinal prospective observational study.SettingTata Memorial Hospital, Mumbai, India, a tertiary cancer care referral centre.ParticipantsPatients, aged ≥65 years, with gastrointestinal, breast or gynaecological stage I–III cancers being planned for curative intent chemotherapy. A total of 270 patients were required for accrual in the study.Exposure(s)Total risk score ranged from 0 (lowest toxicity risk) to 19 (highest toxicity risk).Main outcome(s) and measure(s)The primary endpoint of the study was to evaluate whether the CARG risk score predicted for grade 3–5 toxicities.ResultsThe study cohort of 270 patients had a mean age of 69 (65–83) years, with the most common cancers being gastrointestinal (79%). Fifty-two per cent of patients had atleast one grade 3–5 toxicity. The risk of toxicity was increased with an increasing risk score (42% low risk, 51% medium risk and 79% high risk; p<0.001). There was no association between either Eastern Cooperative Oncology Group (ECOG) performance status (p=0.69) or age-adjusted Charlson Comorbidity Index (p=0.79) risk categories and grade 3–5 chemotherapy toxicities.Conclusions and relevanceThis study validates the CARG risk score in predicting for grade 3–5 toxicities in geriatric oncology patients receiving curative intent chemotherapy and can be considered as the standard of care before planning chemotherapy in every elderly patient.Trial registration numberCTRI/2016/10/007357; Results.

Background Checkpoint inhibitors (Nivolumab and Pembrolizumab) are approved for multiple indications in solid tumors. However access to these therapies is limited in low and middle income countries. Hence we performed an audit to identify accessibility, adverse event rates, compliance, progression free survival and overall survival in solid tumors. Methods This was a single center retrospective analysis of prospective data base of patients with non‐melanoma solid tumors who were treated with immunotherapy from August 2015 to November 2018. Adverse events during immunotherapy were documented and graded using CTCAE (Common terminology criteria for adverse events), v. 4.02. The response rates to immunotherapy, toxicities and the time to onset and resolution of toxicities were also evaluated as secondary endpoints. Results Out of 9610 patients, only 155 patients (1.61%) could receive immunotherapy. The most common malignancies included metastatic non‐small cell lung cancer, metastatic renal cell carcinoma, metastatic urothelial carcinoma and relapsed/recurrent head and neck squamous cell carcinoma. Median overall survival in patients who received immunotherapy in non‐melanoma solid malignancies was 5.37 months (95% CI, 3.73–9.73). Poor performance status at baseline was the only adverse prognostic factor. The median progression free survival was 2.57 months (95% CI, 1.73–3.83). Immunotherapy was well tolerated with most common side effects being fatigue 14.8% and anorexia 5.8%. The cumulative incidence of immune related adverse events like hepatitis, pneumonitis, colitis and nephritis was less than 10%. Conclusion Real‐world data in Indian setting confirms the benefit of immunotherapy in patients with advanced non‐melanoma solid tumors. This is the first and largest real world data of immunotherapy from India. It focuses on efficacy and tolerability of immune check point inhibitors in Indian patients.

Background: There is limited data with regard to the use of modified 5-fluoroural-leucovorin-irinotecan-oxaliplatin (mFOLFIRINOX) in terms of tolerance and enabling total mesorectal excision (TME) of locally advanced rectal adenocarcinomas (LARC) with high-risk characteristics (T4b status, signet ring histology etc) post standard neoadjuvant long course chemoradiation (NACTRT) or short course radiation (SCRT) and chemotherapy. Materials and Methods: Patients with LARC from January 2018 to December 2020 receiving mFOLFIRINOX post NACTRT/SCRT to facilitate TME were evaluated. The primary endpoint was assessment of grade 3 and grade 4 treatment related toxicity and TME rates. Event free survival (EFS), where event was defined as disease progression or recurrence post resection after mFOLFIRINOX, was calculated by Kaplan Meier method. Results: Forty-seven patients were evaluated with a median age of 33 years (Range:18-59), 45% T4b status, 96% radiological circumferential margin (CRM) involved (79% CRM positive post NACTRT/SCRT), 43% extramural venous invasion (n=33) and 36% signet ring histology. 62% had received prior NACTRT and 38% had received SCRT with chemotherapy before receiving mFOLFIRINOX. The most common grade 3 and grade 4 treatment related side effects included diarrhoea (7%), anaemia (4%) and infections (4%). Intended duration of mFOLFIRINOX or beyond was completed in 94% of patients. 60% of patients underwent curative local resection with R0 resection rates of 100% (n=28) and pathological complete response rates of 21%. The most common surgeries done were exenterations and abdominoperineal in 22% and 17% patients respectively. With a median follow up of 19 months, 24 patients had recurred or progressed for a median EFS of 20 months [95% confidence interval (CI): 15-24]. Conclusions: Locally advanced rectal cancers with high-risk characteristics are a niche group of cancers with less-than-optimal outcomes post standard neoadjuvant strategies. mFOLFIRINOX appears to be well tolerated and enables TME in a significant proportion of these patients.

A major shift in the approach to the management of pancreatic ductal adenocarcinomas (PDACs) has been the recognition of the systemic nature of the disease even in clinically and radiologically limited disease stages. The recalcitrant nature of PDAC is intrinsically related to the lack of therapeutic targets and dense surrounding stroma that limits the activity of currently available chemotherapeutic options. However, research is increasingly focusing on intensifying systemic management options in PDAC, resulting in gradual improvements in survival. Currently effective chemotherapeutic regimens like modified 5-fluorouracil-leucovorin-irinotecan-oxaliplatin and gemcitabine-nab-paclitaxel have improved outcomes in resectable and advanced PDAC. An increasing use of these regimens has also resulted in greater conversion of borderline resectable and locally advanced cancers to resection, though the most effective approach in this subgroup is yet to be identified. The current review presents an outline of the basic systemic nature of PDAC and current options of systemic therapy, predominantly chemotherapy .

The data regarding the use of neoadjuvant chemotherapy in technically unresectable head and neck cancer (HNC) is limited and real-world studies are needed to look for the efficacy and toxicities of this approach. This is a retrospective study conducted in the Medical Oncology department of our hospital. All technically unresectable HNC patients who underwent neoadjuvant chemotherapy between May 2018 and May 2020 were included in this analysis. Patients received three-drug regimen docetaxel, cisplatin and 5-fluorouracil (DCF) regimen, two-drug regimens included docetaxel + cisplatin, paclitaxel + carboplatin both weekly and 3-weekly. The resectability assessment was done clinically and radiologically after completing three neoadjuvant cycles. Overall survival was calculated from the first day of chemotherapy to the date of last follow-up or date of death. A total of 119 patients received neoadjuvant chemotherapy during the specified time. Response assessment showed partial response in 41.9% of patients with three-drug regimens and 37.5% of patients with other regimens. Out of 119 patients, 56 (47%) patients were offered radical intent therapy. Resectability was achieved in 32.3% of three-drug regimen patients and 26.1% of other patients. Surgery was feasible in 33 (27.7%) patients, and postoperative radiotherapy and concurrent chemotherapy were done in 30 patients (25.2%), and surgery with only postoperative radiotherapy was done in 3 patients (2.5%). Radical chemoradiotherapy was done in 23 patients (19.3%). The estimated median survival for patients who could undergo surgery was 18 months [95% confidence interval (CI), 14.9-21.0], and nonsurgical patients were 9 months (95% CI, 7.3-10.6) (p = 0.0001). Our study shows that neoadjuvant chemotherapy in technically unresectable HNC patients can make the disease resectable in around one-third of the patients. The patients who could undergo surgery after neoadjuvant chemotherapy had significantly improved survival as compared to those who could not.

The data on outcomes and toxicity in adult Ewing sarcoma (ES) patients, particularly those aged ≥40 years, is exceedingly scarce around the world, particularly in low- and middle-income countries (LMICs) and mandates research. The study involved histologically ascertained ES patients aged ≥40 years who registered at our institute from 2013 to 2018. Prospectively collected data were analysed for overall survival (OS), event-free survival (EFS) and chemotherapy-related toxicities. There were 66 patients, of which 34 were non-metastatic, and 32 were denovo metastatic, recurrent or had doubtful metastasis. At presentation, median age was 46 years, and 42 (63.6%) had extra-skeletal primary and 24 (36.3%) had extremity tumours. Curative treatment was offered to 40 (60.6%) patients. Significant grade 3/4 toxicities in non-metastatic and metastatic cohort, respectively, were febrile neutropenia (61.3%, 37.5%), anaemia (58.1%, 37.5%), thrombocytopenia (45.2%, 25.0%), peripheral neuropathy (25.8%, 12.5%) and dyselectrolytemia (25.8%, 6.25%). Chemotherapy-related toxicity led to death in three patients in the metastatic cohort, versus none in the non-metastatic patients. The 5 year EFS and OS for non-metastatic cohort were 53.8% and 67.8%, while the same for metastatic cohort were 20.7% and 27.5%, respectively. On multivariate analysis, Eastern Cooperative Oncology Group-performance status >2 and metastasis at presentation predicted poorer EFS and OS. Additionally, raised lactate dehydrogenase, larger tumours (>8 cm) and palliative intent treatment predicted worse EFS, while extra-skeletal primary and female gender were indicators of worse OS. Older adult ES patients benefit from aggressive multimodality treatment even in LMIC infrastructure. However, careful patient selection, close monitoring and pertinent dose modifications is imperative due to higher propensity for potential toxicities.

Abstract Background This phase I dose de-escalation study aimed to assess the tolerability, safety, pharmacokinetics (PK), and efficacy of sequentially decreasing doses of sorafenib in combination (SAM) with atorvastatin (A, 10 mg) and metformin (M, 500 mg BD) in patients with advanced hepatocellular carcinoma (HCC). Methods Patients were enrolled in 1 of 4 sequential cohorts (10 patients each) of sorafenib doses (800 mg, 600 mg. 400 mg, and 200 mg) with A and M. Progression from one level to the next was based on prespecified minimum disease stabilization (at least 4/10) and upper limits of specific grade 3-5 treatment-related adverse events (TRAE). Results The study was able to progress through all 4 dosing levels of sorafenib by the accrual of 40 patients. Thirty-eight (95%) patients had either main portal vein thrombosis or/and extra-hepatic disease. The most common grade 3-5 TRAEs were hand-foot-syndrome (grade 2 and grade 3) in 3 (8%) and transaminitis in 2 (5%) patients, respectively. The plasma concentrations of sorafenib peaked at 600 mg dose, and the concentration threshold of 2400 ng/mL was associated with higher odds of achieving time to exposure (TTE) concentrations >75% centile (odds ratio [OR] = 10.0 [1.67-44.93]; P = .01). The median overall survival for patients without early hepatic decompensation (n = 31) was 8.9 months (95% confidence interval [CI]: 3.2-14.5 months). Conclusion The SAM combination in HCC patients with predominantly unfavorable baseline disease characteristics showed a marked reduction in sorafenib-related side effects. Studies using sorafenib 600 mg per day in this combination along with sorafenib drug level monitoring can be evaluated in further trials. (Trial ID: CTRI/2018/07/014865). Sorafenib is a recommended therapeutic option in advanced hepatocellular carcinoma, despite the possibility of treatment-related adverse events. This article assesses the tolerability, safety, pharmacokinetics, and efficacy of sequentially decreasing doses of sorafenib in combination with atorvastatin and metformin in patients with advanced hepatocellular carcinoma.

It has been reported that chemotherapy toxicity is primarily not due to the drugs themselves, but is caused by cell-free chromatin particles (cfChPs) that are released from chemotherapy-induced dying cells. cfChPs from dying cells are readily internalized by healthy cells, wherein they inflict dsDNA breaks and activate inflammatory cytokines. cfChPs can be deactivated by oxygen radicals that are generated upon admixing the nutraceuticals resveratrol (R) and copper (Cu). Pre-clinical studies have shown that administration of R-Cu can reduce chemotherapy toxicity via the generation of oxygen radicals which deactivate cfChPs released from chemotherapy-induced dying cells. We investigated if R-Cu would reduce toxicity of docetaxel-based multi-agent chemotherapy in advanced gastric cancer. This single-arm phase II study was designed to assess the efficacy of orally administered R-Cu in ameliorating toxic side effects, as per National Cancer Institute Common Terminology Criteria for Adverse Events v4.03, in patients with advanced gastric cancer receiving docetaxel-based multi-agent chemotherapy. The primary objective was to reduce the proportion of patients experiencing grade ≥ 3 toxicity from 90 to 70%. Between October 2019 and April 2021, 30 patients, with a median age of 54 years, were enrolled of whom 73% were male. R-Cu treatment did not reduce the overall cumulative incidence of grade ≥ 3 toxicity (77%), or of ≥ 3 haematological toxicity (73%). However, the incidence of non-haematological toxicities comprising hand-foot syndrome ( N  = 4), diarrhoea ( N  = 3) and vomiting ( N  = 1) were markedly reduced (13%). Median progression-free survival (PFS) was 8 months (95% CI: 5.9–10.1), and overall survival (OS) was 16 months (95% confidence interval: 6.3–28.3). A marked reduction in non-haematological toxicities was seen in patients receiving R-Cu compared to historical data without adversely affecting PFS or OS. (292).

Background & objectives: FOLFIRINOX and gemcitabine plus nab-paclitaxel (GN) are the most commonly used regimens in advanced pancreatic ductal adenocarcinomas (PDACs). As there is limited data on comparison of these two regimens, the present study was aimed to compare survivals and tolerance for both regimens through a match-pair analysis. Methods: The data of 350 patients with metastatic and locally advanced PDAC, treated between January 2013 and December 2019, were retrieved. A 1:1 matching, using age and performance status, without replacement was performed by using nearest neighbour matching method. Results: A total of 260 patients (130 modified FOLFIRINOX and 130 GN) were matched. The median overall survival (OS) was 12.98 months [95% confidence interval (CI) 7.257-8.776 months] in modifications of FOLFIRINOX (mFOLFIRINOX) cohort and 12.06 months (95% CI 6.690-8.88 months) in GN group (P=0.080). The incidence of grade 3 and 4 infections, diarrhoea, oral mucositis, and fatigue was higher with mFOLFIRINOX. Patients who received second line therapy had improved OS as compared to those who did not (14.06 vs. 9.07 months, P<0.001). Interpretation & conclusions: GN and mFOLFIRINOX appear to have similar survival outcomes in an unselected match paired patient population with advanced PDAC. A markedly increased incidence of non-myelosuppressive grade 3 and grade 4 side-effects and lack of survival improvements suggest a need for nuanced use of the mFOLFIRINOX regimen. Administration of second-line chemotherapy improves OS in patients with advanced PDAC.
