Background and Purpose: Hypothyroidism is a recognized late adverse event following radiotherapy for head and neck cancer (HNC). In the JCOG1008 trial, we treated patients with high-risk HNC with postoperative chemoradiotherapy. We aimed to elucidate factors associated with hypothyroidism by analyzing the JCOG1008 data., Materials and Methods: In 2012-2018, 261 patients from 28 institutions were enrolled in JCOG1008. Thyroid function tests were conducted to assess hypothyroidism, including free thyroxine (FT4) and thyroid-stimulating hormone assays. Hypothyroidism was defined as Grade 2 or higher in CTCAE v4.0. Various clinical and dosimetric parameters were analyzed. In radiotherapy, there were no dose constraints for the thyroid. Multivariable analysis was conducted on these variables to identify predictive factors for hypothyroidism., Results: The analysis included 162 patients (57 with 3D-CRT and 105 with IMRT), with a median follow-up of 4.7 years (0.3-9.3 years). Among these, 27 (16.7 %) developed hypothyroidism within 2 years after radiotherapy. In a multivariable analysis, the weekly cisplatin [OR=7.700 (CI: 1.632-36.343, p = 0.010)] and baseline FT4 [OR=0.009 (CI: <0.001-0.313, p = 0.010)] were significantly associated with hypothyroidism in the IMRT group. Regarding dosimetric characteristics, V 60Gy [OR=1.069 (CI: 0.999-1.143, p = 0.054)] was potentially associated with the development of hypothyroidism., Conclusion: The study revealed that the incidence of hypothyroidism within 2 years after postoperative chemoradiotherapy for high-risk HNC was 16.7 % based on analytical results from prospective clinical trials., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Background: The National Comprehensive Cancer Network (NCCN) guideline recommends consideration of weekly cisplatin as an alternative option for patients with head and neck cancer undergoing definitive chemoradiation. However, in a recent phase III trial (ConCERT), 20% of patients treated with weekly cisplatin could not receive a total of 200 mg/m 2 , and the association of low adherence to weekly cisplatin and cancer control outcomes remains unclear. To fill this knowledge gap, we performed an observational cohort study of patients with head and neck cancer undergoing definitive chemoradiation with weekly cisplatin., Methods: Our institutional database was queried for patients with non-metastatic head and neck cancer who underwent definitive chemoradiation with weekly cisplatin (40 mg/m 2 ) between November 2007 and April 2023. Adherence to weekly cisplatin was defined as receiving at least 5 cycles with a total cumulative dose of 200 mg/m 2 . Survival outcomes were evaluated using Kaplan-Meier method, log-rank tests, Cox proportional hazard multivariable (MVA) analyses. Logistic MVA was performed to identify variables associated with low adherence to weekly cisplatin. Fine-Gray MVA was performed to analyze failure outcomes with death as a competing event., Results: Among 119 patients who met our criteria, 51 patients (42.9%) had low adherence to weekly cisplatin. Median follow up was 19.8 months (interquartile range 8.8-65.6). Low adherence to weekly cisplatin was associated with worse overall survival (adjusted hazards ratio [aHR] 2.94, 95% confidence interval [CI] 1.58-5.47, p < 0.001) and progression-free survival (aHR 2.32, 95% CI 1.29-4.17, p = 0.005). It was also associated with worse distant failure (aHR 4.55, 95% CI 1.19-17.3, p = 0.03), but not locoregional failure (aHR 1.61, 95% CI 0.46-5.58, p = 0.46). KPS < 90 was the only variable associated with low adherence to weekly cisplatin (adjusted odds ratio [aOR] 2.67, 95% CI 1.10-6.65, p = 0.03)., Conclusion: Our study suggested that over 40% of patients underwent fewer than 5 weekly cisplatin cycles and that low adherence to weekly cisplatin was an independent, adverse prognostic factor for worse survival and distant failure outcomes. Those with reduced adherence to weekly cisplatin were more likely to have poor performance status. Further studies are warranted to improve the adherence to chemotherapy and outcomes., (© 2024.

Cisplatin, one of the most ototoxic anti-neoplastic agents, causes permanent hearing loss in up to 90% of patients. We assessed ototoxicity rates and prospectively collected audiologic outcomes of patients receiving low-dose or high-dose cisplatin with concurrent cochlear-sparing intensity-modulated radiation therapy (IMRT). Patients with head and neck squamous cell carcinoma (HNSCC) receiving definitive or adjuvant cisplatin-based chemoradiotherapy (CRT) were analyzed. Cisplatin was administered either in low doses weekly (40 mg/m 2 ) for up to seven doses or in high doses triweekly (100 mg/m 2 ) for up to three doses. Cochlear-sparing IMRT was delivered in all cases. Audiologic data were prospectively collected before, during, and after treatment completion. The primary endpoint was a hearing change grade of ≥3 after CRT completion. Of the 96 HNSCC patients evaluated, 69 received weekly cisplatin and 58 received definitive CRT. Of patients receiving weekly cisplatin, 13% developed ≥G3 ototoxicity vs. 56% of patients who received triweekly cisplatin ( p < 0.001). In multivariable modeling, the cisplatin dose schedule remained significant (OR: 8.4, 95%CI: 2.8-27.8, p < 0.001) for risk of severe irreversible ototoxicity. Triweekly cisplatin CRT significantly increased the ≥G3 severe irreversible ototoxicity risk compared to low-dose weekly cisplatin, irrespective of the cumulative cisplatin dose, even with the use of cochlear-sparing IMRT. No significant difference in oncologic outcomes was observed between the two schedules.

Background: Tri-weekly cisplatin and radiotherapy (CDDP + RT) is a standard of care for locally advanced head and neck squamous cell carcinoma (LA-HNSCC) but is sometimes challenging to complete in older patients. Weekly CDDP + RT has shown mild toxicity compared to tri-weekly CDDP + RT for LA-HNSCC and is a promising option for older adults. We aimed to report the treatment outcomes and prognostic factors in patients with LA-HNSCC treated with weekly CDDP + RT., Methods: We analyzed patients aged ≥ 70 years who started weekly CDDP + RT for LA-HNSCC between July 2006 and October 2022. LA-HNSCC includes cancer in the oropharynx, hypopharynx, or larynx with a clinical stage of 3 or 4 without distant metastases based on the Union for International Cancer Control staging system 8th edition. The radiation dose of 70 Gy was delivered in 35 fractions by 3-dimensional conformal radiotherapy, intensity-modulated radiotherapy, or proton beam therapy. The primary endpoint was the 3-year overall survival (OS), and the secondary endpoints were the 3-year progression-free survival (PFS) and 3-year cause-specific survival (CSS). The Kaplan-Meier method was used to calculate survival rates, and the log-rank test was used to evaluate statistical significance. A Cox proportional hazards model was used for the multivariate analysis of prognostic factors., Results: The median age of the 49 patients was 72 (range: 70-78) years. The median CDDP dose was 200 (40-280) mg/ m 2 , and 47 patients completed scheduled radiotherapy. Forty-eight patients (98.0%) had a performance status of ≥ 1 at the initial visit. The 3-year OS, PFS, and CSS were 80.9% (95% confidence interval [CI]: 64.8-90.7), 68.3% (95% CI 51.8-81.2), and 85.0% (95% CI 68.7-93.4), respectively. In the multivariate analysis, the cumulative CDDP dose (< 200 or ≥ 200 mg/m 2 ) was a significant factor for OS (hazard ratio: 0.29 [95% CI 0.08-0.97], p = 0.044). There was one case of early mortality. Grade 3 or higher late adverse events were observed in four patients (8.2%)., Conclusions: Weekly CDDP + RT in older patients led to good survival outcomes with an acceptable rate of adverse events. CDDP should be administered at a dose of at least 200 mg/m 2 in older patients. Trial registration Retrospectively registered., (© 2023. The Author(s).)

Purpose: There are no well-recognized guidelines for antiemesis during concurrent chemoradiotherapy (CCRT) for cervical cancer (CC) and nasopharyngeal cancer (NPC) until now. The study was designed to assess the efficacy and safety of fosaprepitant combined with tropisetron and dexamethasone in preventing nausea and vomiting during 5 weeks of fractionated radiotherapy and concomitant weekly low-dose cisplatin chemotherapy in patients with CC or NPC., Methods: Patients with CC or NPC were scheduled to receive fractionated radiotherapy and weekly cisplatin (25-40 mg/m 2 ) chemotherapy for at least 5 weeks. Patients stratified by tumor type and induction chemotherapy were 1:1 randomly assigned to receive fosaprepitant, tropisetron, and dexamethasone or tropisetron plus dexamethasone as an antiemetic regimen. Efficacy was assessed primarily by the cumulative incidence of emesis after 5 weeks of treatment, and safety by adverse events (AEs)., Results: Between July 2020 and July 2022, 116 patients consented to the study of whom 103 were included in this interim analysis (fosaprepitant group [N = 52] vs control group [N = 51]). The cumulative incidence of emesis at 5 weeks (competing risk analysis) was 25% (95% CI 14.2-37.4) for the fosaprepitant group compared with 59% (95% CI 43.9-71.0) for the control group. There was a significantly lower cumulative risk of emesis in the fosaprepitant group (HR 0.35 [95% CI 0.19-0.64]; p < 0.001). Fosaprepitant was well tolerated as the incidences of adverse events in the two groups were comparable., Conclusion: The addition of fosaprepitant to tropisetron plus dexamethasone significantly reduced the risk of nausea and vomiting during 5 weeks of CCRT in patients with CC or NPC, and fosaprepitant was well tolerated., Trial Registration: The trial was registered with ClinicalTrials.gov on October 3, 2022, number NCT05564286., (© 2023.

Background: The current standard of treatment for locally advanced cervical cancer is concurrent chemo-radiation with improved overall survival (OS) by 6% with manageable toxicities. The cisplatin 40 mg/m 2 given weekly is the widely practiced regimen for 4-6 cycles concurrently with irradiation., Materials and Methods: Two hundred and twelve patients with histologically proven squamous cell carcinoma of cervix with stages IIB to IIIB were enrolled between 2007-2011. External beam radiation dose of 45 Gy in 25 fractions was delivered over 5 weeks. Brachytherapy was delivered by manual afterloading cesium-137 (Cs137) low dose brachytherapy (LDR) using modified Fletcher suit intracavitary applicators to a total dose of 30 Gy to Point A or interstitial template to dose of 21 Gy/3 fractions with remote afterloading iridium-192 (Ir192) high dose brachytherapy (HDR). Patients were randomized to arm A receiving 40 mg/m 2 of concurrent cisplatin weekly and arm B receiving 100 mg/m 2 of concurrent cisplatin triweekly., Results: One hundred and nine patients were randomized to weekly cisplatin and one hundred and three patients to triweekly cisplatin at the end of recruitment. At ten years, the OS was higher in the weekly arm (79.8%) compared to triweekly arm (70.9%). Disease free survival (DFS) was almost equal (76.1% and 73.8%) in the weekly and three-weekly arms. There is definite significance in overall DFS with patients receiving the cumulative cisplatin doses of more than 250 mg (p = 0.028). The patients with more than 45 years of age had better overall survival (OS) (79%) with statistical significance 31 (p = 0.020)., Conclusion: Both cisplatin based triweekly and weekly concurrent chemotherapy are equally effective in terms of OS and DFS., Competing Interests: Conflicts of interest None declared., (© 2023 Greater Poland Cancer Centre.)

Concurrent chemoradiotherapy with 3-weekly cisplatin 100 mg/m 2 has been the standard of care for locoregionally advanced head and neck cancer (LA-HNC) with level I evidence. While the outcomes in terms of efficacy have been well established, the toxicity profile, compliance, and real-world applicability has been an area of ongoing concern for this regimen, leading the oncologists to explore weekly cisplatin chemoradiotherapy regimen to potentially address the issue. A review of literature was conducted in Pubmed, Scopus, and Medline to compare and evaluate the present role of weekly cisplatin chemotherapy along with radiotherapy versus 3-weekly cisplatin chemotherapy along with radiotherapy in both adjuvant and definitive settings for locoregionally advanced head and neck cancers. Nasopharyngeal subsites were excluded from the literature review and 50 relevant articles were included in the analysis. Recently published evidences of noninferiority of weekly over 3-weekly cisplatin chemoradiotherapy regimen in definitive as well as adjuvant settings in locoregionally advanced head and neck cancers is highlighted and interpreted. Results supporting and against the above in different publications is elaborated in this article. Trials designed to demonstrate noninferiority of the weekly cisplatin chemoradiotherapy regimen over 3-weekly regimen, especially in definitive setting may conclude the debate in future. A lacunae in the existing literature is noted in the form of lack of superiority trials on the above topic, which may impact future conclusions., (© 2023 Wiley Periodicals LLC.)

Background: Nasopharyngeal carcinoma (NPC) is rare in the UK. The aim of the current study was to investigate survival outcomes for patients with NPC treated with (chemo)radiotherapy using 65 Gy in 30 fractions in a non-endemic region., Materials and Methods: All consecutive 62 patients with histology proven non-metastatic nasopharyngeal carcinoma diagnosed between January 2009 to June 2019 were included in this retrospective analysis., Results: Median age was 59 years (range:19-81). The majority of patients had stage III disease (66.1%). Induction chemotherapy was given in 21% of patients and 82.3% of patients received concomitant systemic therapy. All patients were treated with 65 Gy in 30 fractions. There was disease recurrence in 17.4% patients. The 5-year disease-free, disease-specific and overall survival were 81.9%, 79.2% and 76.4%, respectively. On univariate analysis, disease recurrence was associated with N-stage (p = 0.047) and overall stage group (p = 0.023)., Conclusion: To the best of authors' knowledge, this is the first report of the use of 65 Gy in 30 fractions of radiotherapy ± weekly cisplatin chemotherapy in NPC in a real-world setting. Our results are comparable to that from other non-endemic regions of the world using different dose fractionation of (chemo)radiotherapy. Future randomised control trials are warranted to compare various dose fractionations in these settings., Competing Interests: Conflict of interest None declared., (© 2022 Greater Poland Cancer Centre.)

Introduction  Concurrent chemoradiation with weekly cisplatin in locally advanced head and neck squamous cell carcinoma (LA-HNSCC) is widely practiced in India. Radiation with simultaneous integrated boost intensity-modulated radiotherapy (SIB-IMRT) has the advantage of executing IMRT in single phase with better dose distribution. Material and Methods  150 patients with LA-HNSCC treated between April 2015 and December 2019 were retrospectively evaluated. All patients received 70Gy in 33 to 35 fractions with SIB-IMRT and concurrent weekly cisplatin at a dose of 40 mg/m 2 . Treatment compliance and toxicities were assessed. Overall survival (OS) was evaluated using Kaplan-Meier estimates; univariate and multivariate analysis of prognostic factors were also evaluated. Results  Median age was 58.5 years. Forty-five percent had primary oropharyngeal cancer. Sixty-two percent had T3 disease, 41% had N2 disease, and 51% had stage IV disease. All patients received 70Gy dose of RT. Median chemotherapy cycles were six, 84.7% received 200 mg/m 2 . Acute grade 2 xerostomia was seen in 79%, grade 3 neutropenia, mucositis and pharyngitis were seen in 11, 15, and 21%, respectively. Complete response was seen in 66.6%. At median follow-up of 21.4 months (3-71) OS was 60% and median OS was 33.2 months. Estimated 2 and 3 year OS was 56 and 48%. On univariate analysis, absence of node, N0-N1, stage III, cisplatin use, dose per fraction 2.12Gy ,and complete response showed good OS ( p <0.05). On multivariate analysis dose per fraction 2.12Gy and complete response showed good OS ( p <0.05). Conclusion  Definitive chemoradiation with weekly cisplatin and SIB-IMRT in LA-HNSCC is well tolerated with good clinical outcomes., Competing Interests: Conflict of Interest None declared., (MedIntel Services Pvt Ltd.

Background: Addition of chemotherapy to radiation has improved 5-year survival by 6%. However, the optimal dose and schedule of concurrent cisplatin is not well defined, though widely accepted practice is the weekly schedule of 40 mg/m 2 for 5 weeks. Repeated admissions for weekly cisplatin drain the limited resources in high volume centres. We intended to study the compliance and toxicity of two cisplatin schedules in our patients diagnosed with carcinoma cervix., Materials and Methods: Between 2007-2011, 212 patients, histologically proven squamous cell carcinoma with stages IIB to IIIB were randomized into two arms. All patients were planned for external beam radiotherapy 45 Gy/25 frs over 5 weeks followed by Intracavitary or Interstitial brachytherapy to a total BED dose of 75-85 Gy. Single agent cisplatin given concomitantly, was scheduled weekly (40 mg/m 2 /cycle, 5 cycles) in an arm A and three weekly (100 mg/m 2 /cycle, 2 cycles) in an arm B. Toxicity and compliance were evaluated weekly according to the RTOG guidelines. Analysis of the compiled data was done using SSPS version 20., Results: Of the evaluable 212, 109 patients received weekly cisplatin chemotherapy and 103 patients received three weekly cisplatin. The most common acute toxicity observed was grade I-II leucopoenia. The upper and lower gastrointestinal reactions were high in three weekly arms, which was statistically significant (57% and 42.7%, p < 0.05). Proctitis was observed in 10% of patients in both of the arms and only two patients had Gr1 Cystitis after 6 months of treatment., Conclusions: Tri-weekly cisplatin based concurrent chemoradiation can be adopted in high volume centres with manageable haematological and gastrointestinal acute toxicities., Competing Interests: Conflict of interest None declared., (© 2021 Greater Poland Cancer Centre.)

Background: Patient Reported Outcome (PRO) data comparing bolus (B-CP) with weekly (W-CP) cisplatin concurrent with radiation are lacking., Methods: We performed a retrospective study comparing PRO among 99 patients with head and neck radiation, 26% who received concurrent B-CP and 73% treated with W-CP., Results: W-CP patients had a higher Charlson comorbidity index (CCI) (P = .004). There were no differences in median cisplatin dose, PROs, percutaneous endoscopic gastrostomy (PEG) dependence or hospitalization between arms. Patients with a greater decline in their self-reported dysphagia score were more often PEG dependent at the end of radiation therapy (P = .03). There was also a trend toward PEG dependence with a higher maximum dysphagia score and greater change in aspiration score (P = .06). The maximum decline in white cell count and absolute neutrophil count were greater in the W-CP group (P = .04, P = .01)., Conclusion: Both B-CP and W-CP are well tolerated. PROs do not suggest a benefit to W-CP., (© 2020 Wiley Periodicals LLC.)

Background There is limited data on specific antiemetic protocols for control of chemotherapy-induced nausea/vomiting (CINV) caused by weekly cisplatin regimens. Olanzapine is an active agent against CINV and may offer better control of nausea compared to aprepitant/fosaprepitant-based regimens. The usual antiemetic dose of olanzapine (10 mg for four days) causes problems with drowsiness. A lower dose may be as effective with lesser side effects in patients receiving weekly cisplatin. Objective To assess the control of nausea, vomiting, and occurrence of side effects with a modified olanzapine-based antiemetic regimen among patients with carcinoma of the cervix receiving concurrent cisplatin with pelvic radiotherapy. Setting Tertiary cancer hospital in Southern India. Methods We used a modified regimen "mini-OPD", oral olanzapine (5 mg) days 1 and 2, intravenous palonosetron (0.25 mg) and dexamethasone (12 mg) on day 1 of cisplatin administration in patients with carcinoma of the cervix receiving concurrent chemoradiotherapy with weekly cisplatin (40 mg/m 2 /week). At our centre, these patients remained inpatients throughout chemoradiotherapy. CINV-related outcomes were captured in the patients' records by the treating physician in the subsequent week (up to 6 times per patient depending on the number of cycles). We audited these records to calculate the complete response (CR defined as no emetic episodes and no use of rescue medication) rate. Main outcome measure Grades of nausea, vomiting, and drowsiness as per CTCAE v4.0. Results Data of 65 patients (median age: 48 years) who received mini-OPD regimen (median doses of cisplatin/patient: 4) was available. The CR rate was 55%. Considering all cycles together (217 weekly assessment points), "no nausea" target was attained in 125 (58%) assessments and "no vomiting" in 168 (77%). There were no significant side effects. Conclusions The mini-OPD regimen is an inexpensive, non-toxic and effective regimen for the prevention of CINV in patients receiving weekly cisplatin concurrent with pelvic radiotherapy.

Background: Cisplatin-based chemoradiotherapy is standard of care for locally advanced squamous cell carcinoma of the head and neck. This systemic review compared efficacy and safety of weekly vs triweekly cisplatin in locally advanced squamous cell carcinoma of the head and neck., Methods: Among 1500 prospective studies published from 1970 to 2015, 39 (18 weekly, 21 triweekly) including 3668 patients qualified for inclusion. Clinical outcomes were analyzed using weighted estimates and 2-tailed t test for comparisons; significance level was 0.05., Results: Locoregional control was 58% (CI 53%-63%) vs 61% (CI 56%-65%; P = .7). The 2-year overall survival (OS) was 74% (CI 66%-80%) for weekly vs 67% (64%-69%) triweekly groups (P = .67). The 2-year progression-free survival (PFS) was 69% (CI 59%-77%) for weekly vs 62% (CI 58%-65%) triweekly groups (P = .9). Grade 3 to 5 toxicities were 36% vs 40% (P = .37) in weekly vs triweekly groups., Conclusions: Weekly cisplatin was comparable in efficacy and safety to the triweekly regimen. Our analysis supports the use of weekly or triweekly cisplatin in locally advanced squamous cell carcinoma of the head and neck, with tolerability being a key factor in selection., (© 2019 Wiley Periodicals, Inc.)

Background: The optimal regimen of preoperative chemoradiotherapy for resectable esophageal cancer has not been established. We evaluated accelerated hyperfractionated radiotherapy (RT) concurrent to low-dose weekly cisplatin and continuous infusion fluorouracil (LDCI-FU) followed by esophagectomy in patients with locally advanced squamous cell carcinoma (SCC) of the esophagus., Methods: Patients with clinical stage II or III SCC of the esophagus received cisplatin 30 mg/m 2 /week (days 1, 8, 15), LDCI-FU 300 mg/m 2 /day (days 1-21), and concomitant RT to a dose of 45 Gy (150 cGy/fraction, 2 fractions/day) on tumor and affected lymph nodes, followed by radical esophagectomy., Results: From 1997 to 2012, 64 patients were treated with this regimen. Twenty-four patients (37 %) had grade 3 esophagitis, 18 (28 %) of whom required hospitalization. The risk of hospitalization was reduced by placement of a jejunostomy tube before starting induction chemoradiotherapy. Six patients (9 %) had grade 3-4 neutropenia. Fifty-three patients (83 %) underwent esophageal resection and complete resection was achieved in 45 (70 %). The overall median survival was 28 months (95 % CI: 20.4-35.6) and 5-year survival was 38 %. In the 18 patients attaining a pathological complete response, median survival was 132 months and 5-year survival was 72 %. Positron emission tomography standardized uptake values (PET SUVmax) post-chemoradiotherapy were associated with pathological response (p = 0.03) and survival (p = 0.04)., Conclusions: Intensive preoperative hyperfractionated RT concomitant to low-dose cisplatin and LDCI-FU is effective in patients with locally advanced SCC of the esophagus, with good pathological response and survival and manageable toxicities. Post-chemoradiotherapy PET SUVmax shows promise as a potential prognostic factor.

Background: There is interest in different treatment strategies, including deintensification in good prognosis human papillomavirus-positive (HPV(+)) oropharyngeal squamous cell carcinoma (SCC). We reviewed our experience with weekly cisplatin in low-risk, locoregionally advanced HPV(+) oropharyngeal SCC since late 2009., Methods: Data from patients with low-risk HPV(+) oropharyngeal SCC treated with weekly cisplatin (40 mg/m(2) ) and 70 Gy radiotherapy were collected. Low risk was defined as stage III to IV oropharyngeal SCC excluding T1-2N1, T4 or N3 disease, or N2b to N2c disease in patients with >10 pack-year smoking history., Results: Of 31 patients, the median age was 56 years (range, 41-69 years). All patients completed 70 Gy radiotherapy within 51 days and 84% completed at least 5 cycles of cisplatin. Grade 3 mucositis occurred in 22 patients (71%) and grade 3 febrile neutropenia in 6 patients (19%). No patients required enteral feeding at 12 months. The median follow-up was 30 months (range, 21-57 months) with no recurrences or deaths., Conclusion: Concurrent weekly cisplatin is relatively well-tolerated and associated with excellent disease control in low-risk, locoregionally advanced HPV(+) oropharyngeal SCC. © 2015 Wiley Periodicals, Inc.

Aim and Objective: Weekly administration of cisplatin (cis-diamminedichloroplatinum [CDDP]) appears more feasible and substantially more popular than the 3 weekly schedules due to better compliance. Different concurrent cisplatin schedules have been attempted including a daily schedule. We did a comparison of two consecutive single arm studies, i.e., use of weekly cisplatin versus daily cisplatin when used with concurrently with a moderately accelerated radiotherapy (RT) schedule., Patients and Methods: Two prospective feasibility, safety and efficacy studies were carried out consecutively within the department. The weekly CDDP study was done from August 2003 to August 2005 and daily CDDP study was conducted from November 2005 to June 2007. Both studies included locally advanced stage III and IV squamous cell carcinoma of the head and neck region with RT dose of 70 Gy. Concurrent single-agent cisplatin was administered weekly (35 mg/m(2)) in the first and daily (6 mg/m(2)) in the second study., Results: Weekly cisplatin study had 68 and daily CDDP study had 52 patients. The median follow-up in the two studies was 93 and 63 months, respectively. Compliance in the two studies was comparable. Acute Grade III/IV mucositis and dysphagia were significantly higher in weekly cisplatin study. Late Grade II/III toxicities such as xerostomia, dysphagia, ototoxicity and nephrotoxicity were similar. The 5 years locoregional control was 18% and 25% and 5 years overall survival rate was 32% and 31% in weekly and daily cisplatin studies, respectively., Conclusions: Modest acceleration along with either weekly or daily cisplatin, whichever is possible in one's setup, is do-able, provided due attention is paid to patient selection and supportive care.

Background: The purpose of this report was to present the results of accelerated radiotherapy (RT) with concomitant weekly cisplatin in head and neck cancer., Methods: One hundred six patients received concomitant cisplatin 40 mg/m(2) weekly with accelerated RT up to a dose of 68 Gy over 5.5 weeks., Results: Ninety-nine percent of the patients received planned RT and 90% received ≥5 cycles of cisplatin. Moist desquamation of skin developed in 45% and confluent mucositis in 82%. Feeding tubes were required in 79% of the patients, and after 12 months in 4%. One patient developed nephrotoxicity. Three-year locoregional control, disease-free survival (DFS), and overall survival (OS) were 72%, 54%, and 61%, respectively. Human papillomavirus (HPV) status was positive on polymerase chain reaction (PCR) and p16 in 11 of 50 patients with oropharyngeal carcinoma. Three-year OS was 81% and 66% in HPV-positive versus HPV-negative patients with oropharyngeal carcinoma., Conclusion: Concomitant weekly cisplatin 40 mg/m(2) with accelerated RT was well tolerated and treatment compliance was high. © 2015 Wiley Periodicals, Inc.

Objective: The use of non-platinum drugs in concurrent chemoradiation in carcinoma cervix has not been well explored and hence a two arm study was planned to compare the outcome of concomitant cisplatin or gemcitabine in locally advanced carcinoma cervix., Methods: Thirty six patients were evaluated in this study for response rates and complications. These patients were divided into two arms, sixteen patients in the cisplatin arm and twenty patients in the gemcitabine arm. Cisplatin and gemcitabine were given as i.v. infusion at doses of 40 mg/m(2) and 150 mg/m(2) respectively for five weeks concomitant with radiotherapy. All patients had received pelvic radiotherapy to a dose of 50 Gy/25 fraction/5 weeks by four field box technique followed by high-dose-rate brachytherapy (3 sessions, each of 7.5 Gy to point A)., Results: Median follow up was of 10.4 months (range, 3 to 36 months) and 10.9 months (range, 2 to 49 months) in the cisplatin and gemcitabine arms, respectively. At first follow up, 68.8% in the cisplatin arm and 70% in the gemcitabine arm had achieved complete response (p=0.93). Similar response rates were noted in different stages in both arms. None of the patients except one developed grade 4 toxicity. Similar toxicity profiles were observed in both arms. Local disease control, distant disease free survival and overall survival was 68.8% vs. 70%, 93.8% vs. 85%, 68.8% vs. 60% in the cisplatin and gemcitabine arms, respectively., Conclusion: Weekly gemcitabine had similar disease control and tolerable toxicity profile with cisplatin. Gemcitabine may be used as an alternative to cisplatin in patients with compromised renal function.
