RESUMO
INTRODUCTION: Urachal cancer (UC) is a rare genitourinary malignancy arising from the urachus, an embryonic remnant of the placental allantois. Its diagnosis remains ambiguous with late-stage cancer detection and represents a highly aggressive disease. Due to its rarity, there is no clear consensus on molecular signatures and appropriate clinical management of UC. CASE REPORT: We report a 45-year-old man with recurrent urachal adenocarcinoma (UA) treated with cystectomies, chemotherapy, and radiotherapy. The patient initially presented with hematuria and abdominal pain. Imaging revealed a nodular mass arising from the superior wall of the urinary bladder and extending to the urachus. Biopsy results suggested moderately differentiated UA with muscle layer involvement. The tumor recurred after 20 months, following which, another partial cystectomy was performed. Repeat progression was noted indicating highly aggressive disease. Targeted next-generation sequencing revealed the presence of EIF3E::RSPO2 fusion, along with BRAF and TP53 mutations, and EGFR gene amplification. This is the first case reporting the presence of this fusion in UA. Palliative medication and radiotherapy were administered to manage the disease. CONCLUSION: Current treatment modality of surgery may be effective in the early stages of recurrent UA; however, a standard chemotherapy and radiotherapy regimen is yet to be determined for advanced stages. The detection of the rare EIF3E::RSPO2 fusion warrants further studies on the significance of this variant as a possible therapeutic target for improved clinical management.

BACKGROUND: 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. METHODS: 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. RESULTS: 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). INTERPRETATION: 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.

No study has unequivocally proven that chemotherapy prolongs overall survival (OS) in advanced esophageal cancer. We conducted a Phase III randomized study in first-line advanced unresectable/metastatic esophageal/GEJ cancer. Patients aged 18-70 years, with performance status 0-2, were randomized to best supportive care (BSC) alone, or BSC with weekly paclitaxel 80 mg/m2. BSC comprised, as indicated, education, counselling, radiation, stenting, feeding tube placement, nutritional supplementation, medications like analgesics, and referral to a support group and palliative care. The primary endpoint was OS; secondary endpoints included progression free survival (PFS), response, toxicity, and QoL. Between May 2016-December 2020, we recruited 281 patients: 143 to chemotherapy and 138 to BSC. Histopathology was squamous in 269 (95.7%) patients. Median number of paclitaxel doses was 12 (IQR, 7-23). Median OS was 4.2 months (95% CI, 3.42-5.32) in BSC, and 9.2 months (95% CI, 8.02-10.48) in chemotherapy; HR, 0.49 (95% CI, 0.39-0.64); p < .001. As compared to BSC, chemotherapy increased response (2.9% to 39%), median PFS (2.1 to 4.2 months), 1-year OS (11% to 32%), 2-year OS (0 to 9%), median dysphagia-free survival (2.9 to 14.8 months), and global and esophagus-specific QoL, without significantly increasing all-grade or grade ≥3 toxicities. Using ESMO clinical benefit scale and ASCO Value Framework, palliative chemotherapy scored as having "substantial value." Our study provides the first level 1 evidence that chemotherapy prolongs survival in advanced esophageal/GEJ carcinoma. BSC alone is no longer appropriate. Weekly paclitaxel is an attractive option, especially in LMICs with limited access to immunotherapy.
RESUMO
INTRODUCTION: Primary pulmonary salivary gland-type tumours (PPSGT) are rare lung neoplasms arising from submucosal seromucinous glands in the central airway. METHODS AND RESULTS: We retrospectively analysed the clinicopathological features of 111 PPSGTs diagnosed at our institute between 2003 and 2021. The mean age at diagnosis was 43.8 years(range 6-78 years) and a male-to-female ratio of 2:1. On imaging, 92 % of cases had centrally located tumours and 37.3 % were early stage. The histopathological types included 70 cases (63 %) of mucoepidermoid carcinoma (MEC), 31 cases (27.7 %) of adenoid cystic carcinoma (ADCC), two cases of myoepithelial carcinoma, one case each of acinic cell carcinoma (ACC), clear cell carcinoma (CCC), epithelial myoepithelial carcinoma (EMC) and 5 others [including adenocarcinoma of minor salivary gland origin(n = 3), carcinoma with sebaceous differentiation(n = 1) and poorly differentiated carcinoma of salivary gland type(n = 1)]. The size of the tumours found in the resection specimens ranged from 1 cm to 13 cm, with an average size of 4.9 cm. High-risk attributes such as lymphovascular invasion (LVI), perineural invasion (PNI), pleural involvement, positive resection margins, and nodal metastasis were identified in 15.3 %, 15.3 %, 13.6 %,15.2 % and 6.7 % of cases, respectively. These attributes were found to be more frequent in ADCC than in MEC. Surgery was the main treatment modality [68/84 (80 %) cases]. ADCC cases had more recurrence and distant metastasis than MEC cases. The 3- year overall-survival (OS) and recurrence-free survival(RFS) were better in patients with age lesser than 60 years(p-value <0.0001), low pT stage (p-value 0.00038) and lower grade of MEC(p-value-0.0067). CONCLUSION: It is crucial to have an acquaintance with the morphologic spectrum and immunophenotypic characteristics of PPSGT to recognize them in this unusual location. In tandem, it is crucial to differentiate them from conventional primary non-small cell lung carcinoma, as the management protocols and prognostic implications differ significantly.

The real-world data on short course of immune checkpoint inhibitor (ICI) use are sparse and merit exploration. A multicentric observational study on the safety and efficacy of ICI in oncology patients between August 2014 and October 2020 involves 1011 patients across 13 centers in India. The median age was 59 (min 16-max 98) years with male preponderance (77.9%). The predominant cohort received short-course ICI therapy; the median number of cycles was 5 (95% confidence interval [CI] 1-27), and the median duration of therapy was 3 (95% CI 0.5-13) months. ICIs were used commonly in the second and third line setting in our study (66.4%, n = 671). Objective response rate (complete or partial response) was documented in 254 (25.1%) of the patients, 202 (20.0%) had stable disease, and 374 (37.0%) had progressive disease. The clinical benefit rate was present in 456 (45.1%). Among the patients whom ICI was stopped (n = 906), the most common reason for cessation of ICI was disease progression (616, 68.0%) followed by logistic reasons like financial constraints (234, 25.82%). With a median follow-up of 14.1 (95% CI 12.9-15.3) months, there were 616 events of progression and 443 events of death, and the median progression free survival and overall survival were 6.4 (95% CI 5.5-7.3) and 13.6 (95% CI 11.6-15.7) months, respectively, in the overall cohort. Among the immune-related adverse events, autoimmune pneumonitis (29, 3.8%) and thyroiditis (24, 2.4%) were common. Real-world multicentric Indian data predominantly with short-course ICI therapy have comparable efficacy/safety to international literature with standard ICI therapy.

BACKGROUND: Anti-EGFR-based therapies have limited success in HNSCC patients. Predictive biomarkers are needed to identify the patients most likely to benefit from these therapies. Here, we present predictive and prognostic associations of different cancer stem cell markers in HPV-negative locally advanced (LA) HNSCC patients. METHODS: Pretreatment tumour tissues of 404 HPV-negative LA-HNSCCs patients, a subset of-phase 3-randomised study comparing cisplatin-radiation(CRT) and nimotuzumab plus cisplatin-radiation(NCRT) were examined. The expression levels of CD44, CD44v6, CD98hc, ALDH1A1, SOX2 and OCT4A were evaluated using immunohistochemistry. Progression-free survival(PFS), loco-regional control(LRC),- and overall survival(OS) were estimated by Kaplan-Meier method. Hazard ratios were estimated by Cox proportional hazard models. RESULTS: NCRT showed significantly improved OS with low membrane expression of CD44 compared to CRT [HR (95% CI) = 0.63 (0.46-0.88)]. Patients with low CD44v6 also showed better outcomes with NCRT [LRC: HR (95% CI) = 0.25 (0.10-0.62); OS: HR (95% CI) = 0.38 (0.19-0.74)]. No similar benefit with NCRT observed in patients with high CD44 or CD44v6 expression. Bootstrap resampling confirmed the predictive effect of CD44 (Interaction P = 0.015) and CD44v6 (Interaction P = 0.041) for OS. Multivariable Cox analysis revealed an independent negative prognostic role of CD98hc membrane expression for LRC [HR (95% CI) = 0.63(0.39-1.0)] and OS[HR (95% CI) = 0.62 (0.40-0.95)]. CONCLUSIONS: CD44 and CD44v6 are potential predictive biomarkers for NCRT response. CD98hc emerged as an independent negative prognostic biomarker.

OBJECTIVE: To assess the response of chemotherapy on the primary tumor, compare it with the response in retroperitoneal disease, and study factors associated with pathological complete response. METHODS: We conducted a retrospective audit of all high inguinal orchidectomies (HIOs) performed after chemotherapy between 2012 and 2019 at a tertiary cancer center in India. Patient characteristics and histopathological response were extracted from electronic medical records, and predictors of testicular disease response were assessed. RESULTS: Of the 260 retroperitoneal lymph node dissections (RPLNDs) performed in the study period, 37 HIOs (14.23%) were carried out after chemotherapy. The median age of presentation was 28 years (16-41). Histopathology was divided into a viable tumor, mature teratoma, and necrosis/scarring. Residual disease was seen in 17 RPLND (46.0%) and 18 HIO (48.6%) specimens respectively. Of these 18, three patients had a residual viable tumor in the testis, and the remaining had a mature teratoma. Clinico-radiological assessment showed an average reduction of 61% in testicular disease size following chemotherapy. On orchidectomy histopathological assessment, the median tumor size was 9, 4, and 1.5 cm in specimens with a viable tumor, mature teratoma, and necrosis/scarring, respectively. CONCLUSIONS: A low threshold for upfront chemotherapy in patients with a high disease burden may be considered as tumors within the testis respond to chemotherapy in more than half of the patients. Discordance rates of residual cancer in RPLND and HIO specimens exist but post-chemotherapy tumor size in testis correlates with the presence of a residual viable tumor.

BACKGROUND: Outcome and toxicity data in adolescent-adult Ewing sarcoma (AA-ES) patients are sparse and merits exploration. METHODS: Histopathologically confirmed, nonmetastatic AA-ES patients, who received standard institutional combination chemotherapy regimen (Ewing's family of tumors-2001 [EFT-2001]) comprising of ifosfamide plus etoposide and vincristine, doxorubicin plus cyclophosphamide, lasting a total of 12 months between 2013 and 2018, were analyzed for treatment-related toxicities, event-free survival (EFS), and overall survival (OS). RESULTS: There were 235 patients (primary safety cohort [PSC]) with median age of 23 (15-61) years; 159 (67.7%) were males, 155 (65.9%) had skeletal primary and 114 (48.5%) had extremity tumors. One hundred ninety-six (83.4%) were treatment naïve (primary efficacy cohort [PEC]) and of these 119 (60.7%) had surgery. In PEC, at a median follow-up of 36.4 (interquartile range [IQR] 20-55) months, estimated 3-year EFS and OS were 67.3% (95% CI 60.3-75.1%) and 91.1% (95% CI 86.7-95.7%), respectively. Of these, 158 (80.6%) complying with intended treatment, at a median follow-up of 39 (IQR 26-57) months had an estimated 3-year EFS of 68.2% (95% CI 60.3-76.1%). In multivariable analysis, good prognostic factors included longer symptom(s) duration (HR 0.93, 95% CI 0.86-0.994), ≥99% necrosis (HR 0.30, 95% CI 0.11-0.77), and treatment completion (HR 0.32, 95% CI 0.14-0.74). Among PSC, grade 3-4 toxicities were febrile neutropenia (119, 50.6%), anemia (130, 55.3%), peripheral neuropathy (37, 15.7%), with three (1.3%) chemo-toxic deaths. CONCLUSIONS: The outcomes of AA nonmetastatic ES patients treated with EFT-2001 regimen were comparable to those reported by others, with acceptable toxicity. This regimen can be considered a standard of care in AA-ES.

BACKGROUND: Primary mediastinal germ tumours (PMGCT) constitute, a mere 3-4% of all germ cell tumours (GCT). Although they account for approximately 16% of mediastinal tumours in adults and 19-25% in children as per western literature, there is hardly any large series on PMGCT reported from the Indian subcontinent. DESIGN: We have retrospectively analysed clinicopathological features of 98 cases of PMGCT diagnosed over 10 years (2010-2019) from a tertiary-care oncology centre. RESULTS: The study group (n = 98) comprised predominantly of males (n = 92) (M:F ratio-15:1), with an age range between 3 months to 57 years (median: 25 years). The tumours were predominantly located in the anterior mediastinum (n = 96). Broadly, Non-seminomatous germ cell tumours (NSGCT) were more common (n = 73, 74%) compared to pure seminoma (n = 25, 26%). Mixed NSGCT was the most common histological subtype (n = 30) followed by pure mature teratoma (n = 18), pure Yolk sac tumour (n = 13), mixed seminoma and NSGCT (n = 5), pure immature teratoma (n = 3) and GCT; NOS (n = 4). Interestingly, all female patients had exclusive teratomas. Nine cases revealed secondary somatic malignancy (5 carcinomas and 4 sarcomas). The majority of patients received neoadjuvant chemotherapy (n = 71). Surgical excision was performed in 60 patients. Follow up was available in 68 patients. NSGCT showed a poor prognosis as compared to seminoma (p value = 0.03) and tumours with somatic malignancies had a more aggressive clinical course. CONCLUSION: PMGCT was seen predominantly in young adult males and somatic malignancies were noted in as high as 9% of cases. Patient with somatic malignancy have aggressive clinical course, hence, extensive sampling and careful histopathological evaluation are recommended for the identification and definitive characterization.

BACKGROUND: Anti-EGFR-based therapies have limited success in HNSCC patients. Predictive biomarkers are greatly needed to identify the patients likely to be benefited from these targeted therapies. Here, we present the prognostic and predictive association of biomarkers in HPV-negative locally advanced (LA) HNSCC patients. METHODS: Treatment-naive tumour tissue samples of 404 patients, a subset of randomised Phase 3 trial comparing cisplatin radiation (CRT) versus nimotuzumab plus cisplatin radiation (NCRT) were analysed to evaluate the expression of HIF1α, EGFR and pEGFR by immunohistochemistry and EGFR gene copy change by FISH. Progression-free survival (PFS), locoregional control (LRC) and overall survival (OS) were estimated by Kaplan-Meier method. Hazard ratios were estimated by Cox proportional hazard models. RESULTS: Baseline characteristics of the patients were balanced between two treatment groups (CRT vs NCRT) and were representative of the trial cohort. The median follow-up was of 39.13 months. Low HIF1α was associated with better PFS [HR (95% CI) = 0.62 (0.42-0.93)], LRC [HR (95% CI) = 0.56 (0.37-0.86)] and OS [HR (95% CI) = 0.63 (0.43-0.93)] in the CRT group. Multivariable analysis revealed HIF1α as an independent negative prognostic biomarker. For patients with high HIF1α, NCRT significantly improved the outcomes [PFS:HR (95% CI) = 0.55 (0.37-0.82), LRC:HR (95% CI) = 0.55 (0.36-0.85) and OS:HR (95% CI) = 0.54 (0.36-0.81)] compared to CRT. While in patients with low HIF1α, no difference in the clinical outcomes was observed between treatments. Interaction test suggested a predictive value of HIF1α for OS (P = 0.008). CONCLUSIONS: High HIF1α expression is a predictor of poor clinical response to CRT in HPV-negative LA-HNSCC patients. These patients with high HIF1α significantly benefited with the addition of nimotuzumab to CRT.

We need to make choices on a daily basis in our practice of medical oncology. In regular times, these choices are evidence-based and backed by science. However, during emergency situations like the current COVID pandemic, these choices are not just tougher to make, but come with the added burden of inadequate evidence to base them on. We attempt to discuss the various issues involved in making difficult choices.

BACKGROUND: There are limited data on the role of chemotherapy in patients with small cell lung cancer (SCLC) and poor performance status (PS). METHODS: This was a retrospective analysis of a prospective observational study in patients with SCLC and PS 3 or 4. We recorded the initial therapy, symptom improvement, response rate, overall survival (OS), and the impact of various factors on OS. RESULTS: From June 2010 to August 2019, we enrolled 234 patients; 185 (79%) with PS 3 and 49 (21%) PS 4. Initial therapy was best supportive care (BSC) in 49 patients (21%), standard full dose chemotherapy in 31 (13%), and attenuated chemotherapy in 154 (66%). In 89% patients treated with attenuated chemotherapy, symptom-relief occurred at a median of 3 days (IQR, 1-7). Grade 3 and higher toxicities developed in 60% patients treated with initial attenuated chemotherapy, commonly hyponatremia in 39%, neutropenia in 16%, anemia in 11%, and infection in 10%. Grade 3 and higher toxicities as a result of standard chemotherapy occurred in 89% patients treated with upfront standard full dose chemotherapy compared to 69% of patients who received initial attenuated chemotherapy with subsequent treatment escalation. Overall, there were 6 (2.6%) toxic deaths. The response rate to chemotherapy was 77%. The median OS of the patients who received any chemotherapy was significantly longer at 6 months (95% CI, 4.8-7.2) compared to 1 month (95% CI, 0.4-1.6 months) in patients who were managed with BSC, p < 0.001; hazard ratio, 0.39 (95% CI, 0.27-0.56). The disease stage, lactate dehydrogenase level, and receipt of chemotherapy significantly impacted survival. CONCLUSION: Chemotherapy prolongs survival in patients with SCLC and poor PS. Administering an initial attenuated chemotherapy regimen followed by standard full-dose chemotherapy when the PS improves may lower toxicity and improve tolerance.

PURPOSE: Patients of non-small cell lung cancer (NSCLC) with brain metastases have limited treatment options. High-dose erlotinib (HDE) and gefitinib (HDG) have been tried in the past. This study investigates the cerebrospinal fluid (CSF) disposition and safety of both, high-dose erlotinib and gefitinib regimens. METHODS: Eleven and nine patients were treated with erlotinib and gefitinib, respectively. All patients received 1 week of standard dose of erlotinib (150 mg OD) or gefitinib (250 mg OD), followed by the high dose (1500 mg weekly for erlotinib and 1250 mg OD for gefitinib) from day 8. Blood and CSF samples were collected on days 7 and 15, 4 h after the morning dose and drug levels determined using LC-MS/MS. Adverse events were documented as per CTCAE 4.03 till day 15. RESULTS: Pulsatile HDE and daily HDG resulted in 1.4- and 1.9-fold increase in CSF levels, respectively. A constant 2% CSF penetration rate was observed across both doses of erlotinib, while for gefitinib the penetration rate for high dose was half that of the standard dose suggesting a nonlinear disposition. Three patients on HDE treatment discontinued treatment after the first dose due to intolerable toxicities, whereas HDG was better tolerated with no treatment discontinuations. Since CSF disposition of gefitinib followed saturable kinetics, a lower dose of 750 mg was found to achieve CSF concentrations comparable to that of the 1250 mg dose. CONCLUSIONS: HDG was better tolerated than HDE. CSF disposition of gefitinib was found to be saturable at a higher dose. Based on these findings, the dose of 750 mg OD should be considered for further evaluation in this setting.

BACKGROUND: Because the addition of nimotuzumab to chemoradiation in patients with locally advanced head and neck cancer improved outcomes in a phase 2 study, the authors conducted a phase 3 study to confirm these findings. METHODS: This open-label, investigator-initiated, phase 3, randomized trial was conducted from 2012 to 2018. Adult patients with locally advanced head and neck cancer who were fit for radical chemoradiation were randomized 1:1 to receive either radical radiotherapy (66-70 grays) with concurrent weekly cisplatin (30 mg/m2 ) (CRT) or the same schedule of CRT with weekly nimotuzumab (200 mg) (NCRT).The primary endpoint was progression-free survival (PFS); key secondary endpoints were disease-free survival (DFS), duration of locoregional control (LRC), and overall survival (OS). An intent-to-treat analysis also was performed. RESULTS: In total, 536 patients were allocated equally to both treatment arms. The median follow-up was 39.13 months. The addition of nimotuzumab improved PFS (hazard ratio [HR], 0.69; 95% CI, 0.53-0.89; P = .004), LRC (HR, 0.67; 95% CI, 0.50-0.89; P = .006), and DFS (HR, 0.71; 95% CI, 0.55-0.92; P = .008) and had a trend toward improved OS (HR, 0.84; 95% CI, 0.65-1.08; P = .163). Grade 3 through 5 adverse events were similar between the 2 arms, except for a higher incidence of mucositis in the NCRT arm (66.7% vs 55.8%; P = .01). CONCLUSIONS: The addition of nimotuzumab to concurrent weekly CRT improves PFS, LRC, and DFS. This combination provides a novel alternative therapeutic option to a 3-weekly schedule of 100 mg/m2 cisplatin in patients with locally advanced head and neck cancer who are treated with radical-intent CRT.

BACKGROUND: Three-weekly high-dose cisplatin (100 mg/m2) is considered the standard systemic regimen given concurrently with postoperative or definitive radiotherapy in locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN). However, due to unsatisfactory patient tolerance, various weekly low-dose schedules have been increasingly used in clinical practice. The aim of this meta-analysis was to compare the efficacy, safety, and compliance between these two approaches. MATERIALS AND METHODS: We systematically searched literature for prospective trials of patients with LA-SCCHN who received postoperative or definitive conventionally fractionated concurrent chemoradiation. Radiation doses were usually 60-66 gray (Gy) in the postoperative setting and 66-70 Gy in the definitive setting. Standard, three-weekly high-dose cisplatin (100 mg/m2, 3 doses) was compared with the weekly low-dose protocol (≤50 mg/m2, ≥6 doses). The primary endpoint was overall survival. Secondary outcomes comprised response rate, acute and late adverse events, and treatment compliance. RESULTS: Fifty-two studies with 4,209 patients were included in two separate meta-analyses according to the two clinical settings. There was no difference in treatment efficacy as measured by overall survival or response rate between the chemoradiation settings with low-dose weekly and high-dose three-weekly cisplatin regimens. In the definitive treatment setting, the weekly regimen was more compliant and significantly less toxic with respect to severe (grade 3-4) myelosuppression (leukopenia p = .0083; neutropenia p = .0024), severe nausea and/or vomiting (p < .0001), and severe nephrotoxicity (p = .0099). Although in the postoperative setting the two approaches were more equal in compliance and with clearly less differences in the cisplatin-induced toxicities, the weekly approach induced more grade 3-4 dysphagia (p = .0026) and weight loss (p < .0001). CONCLUSION: In LA-SCCHN, current evidence is insufficient to demonstrate a meaningful survival difference between the two dosing regimens. Prior to its adoption into routine clinical practice, the low-dose weekly approach needs to be prospectively compared with the standard three-weekly high-dose schedule. IMPLICATIONS FOR PRACTICE: Given concurrently with conventional radiotherapy in locally advanced head and neck cancer, high-dose three-weekly cisplatin has often been replaced with weekly low-dose infusions to increase compliance and decrease toxicity. The present meta-analysis suggests that both approaches might be equal in efficacy, both in the definitive and postoperative settings, but differ in toxicity. However, some toxicity data can be influenced by unbalanced representation, and the conclusions are not based on adequately sized prospective randomized studies. Therefore, low-dose weekly cisplatin should not be used outside clinical trials but first prospectively studied in adequately sized phase III trials versus the high-dose three-weekly approach.

PURPOSE: Early palliative care is beneficial in advanced lung cancer patients. We aimed to assess the feasibility of introducing early palliative care in ambulatory advanced lung cancer patients in an Indian tertiary cancer center. METHODOLOGY: In a longitudinal, single-arm, and single-center study, fifty patients were recruited and followed up every 3-4 weeks for 6 months, measuring the symptom burden using Edmonton Symptom Assessment Scale (ESAS) and quality of life (QoL) with European Organization for Research and Treatment of Cancer-QoL tools. The primary end point of feasibility was that at least 60% of the patients should complete 50% of the planned palliative care visits and over 50% of the patients should complete QoL questionnaires. Analysis was done using Statistical Package for the Social Sciences version 20. RESULTS: Twenty-four of fifty patients (48%) completed the planned follow-up visits. All patients completed the questionnaires at baseline and 31 (62%) at their follow-up visits. The patients' main reasons for not following up in the hospital palliative care clinic were logistics and fatigue. Tiredness, pain, and appetite loss were the highest rated symptoms at baseline (ESAS scores 3, 2.2, and 2.1, respectively). Improvement in pain and anxiety scores at follow-up visits 1 and 2 was significant (P < 0.05). Scores on QoL functioning scales improved during the follow-up period. CONCLUSIONS: We did not meet the feasibility criteria for the introduction of early palliative care in our advanced lung cancer patients in a resource-limited country.
RESUMO
Locally advanced oral cavity cancers are treated with a multi-modality approach. Surgery is the most efficient local modality in comparison to chemoradiation in oral cancers. Preoperative chemotherapy has failed its expectations to improve disease-free survival or overall survival in resectable oral cancers. Its use as an organ preservation tool is being studied. Induction chemotherapy followed by assessment for surgery is an appropriate option for borderline resectable or technically unresectable oral cancer. Metronomic chemotherapy is being studied as a bridge to surgery and as adjuvant chemotherapy in locally advanced oral cancers. The role of induction chemotherapy in unresectable oral cancers is unproven. Metronomic chemotherapy has shown improved progression-free survival and overall survival in oral cancers in comparison to intravenous cisplatin. A phase 3 study for confirmation of this finding has begun.
