RESUMO
BACKGROUND: Population-based cancer survival is a key indicator for assessing the effectiveness of cancer control by a health care system in a specific geographic area. Breast cancer is the most common cancer among women in India, accounting for over one quarter of all female cancers. The objective of this study was to estimate the 5-year survival of female patients who were diagnosed with breast cancer between 2012 and 2015 from the existing Population-Based Cancer Registries (PBCRs) in India. METHODS: In total, 17,331 patients who had breast cancer diagnosed between 2012 and 2015 from 11 PBCRs were followed until June 30, 2021. Active methods were used to track the vital status of registered breast cancer cases. The study conducted survival analysis by calculating the difference between the date of first diagnosis and the date of death or censoring to estimate observed survival and relative survival using the actuarial survival approach and the Ederer-II approach, respectively. RESULTS: The 5-year age-standardized relative survival (95% confidence interval [CI]) of patients with breast cancer was 66.4% (95% CI, 65.5%-67.3%). Mizoram (74.9%; 95% CI, 68.1%-80.8%), Ahmedabad urban (72.7%; 95% CI, 70.3%-74.9%), Kollam (71.5%; 95% CI, 69.2%-73.6%), and Thiruvananthapuram (69.1%; 95% CI, 67.0%-71.2%) had higher survival rates than the national average. Conversely, Pasighat had the lowest survival rate (41.9%; 95% CI, 14.7%-68.6%). The 5-year observed survival rates for localized, regional, and distant metastasis in the pooled PBCRs were 81.0%, 65.5%, and 18.3%, respectively. CONCLUSIONS: The overall disparity in survival rates was observed across 11 PBCRs, with lower survival rates reported in Manipur, Tripura, and Pasighat. Therefore, it is imperative to implement comprehensive cancer control strategies widely throughout the country.

A notable finding is that Kerala's capital Thiruvananthapuram has shown an increasing trend in lung cancer (LC) incidence. Long-term exposure to air pollution is a significant environmental risk factor for LC. This study investigated the spatial association between LC and exposure to air pollutants in Thiruvananthapuram, using Spatial Lag Model (SLM), Spatial Error Model (SEM), and Geographically Weighted Regression (GWR). The results showed that overall LC incidence rate was 111 per 105 males (age >60 years), whereas spatial distribution map revealed that 48% of the area had an incidence rate greater than 150. The results revealed a significant association between PM2.5 and LC. SLM was identified as the best model that predicted 62% variation in LC. GWR model improved model performance and made better local predictions in the southeastern parts of the study area. This study explores the effectiveness of spatial regression techniques for dealing spatial effects and pinpointing high-risk areas.
RESUMO
Background: Thyroid cancer (TC) is the most common endocrine cancer and has been increasing over the past decades worldwide. A notable finding is that Kerala's capital Thiruvananthapuram ranks the first among men and the second highest among women in the incidence of TC in India. Reasons for this increase have not been established. Objectives: Here, we investigated the spatiotemporal pattern of TC incidence in Thiruvananthapuram. Materials and Methods: TC incidence data (n = 1937) of Population Based Cancer Registry Thiruvananthapuram, Kerala, India, between 2012 and 2016, were analyzed for identifying geographical patterns by spatial methods, temporal methods for studying spatial variation in TC incidence, distribution of age, gender, and histology in lowland (coastal), midland, and highland. Results: Spatial clustering of TC incidence was identified consistently near the coastal region based on all geospatial analyses. 56.9%, 23.9%, and 19.2% of TC cases were observed in the coastal, midland, and highland areas, respectively. A significant clustered pattern of TC incidence was revealed by Moran's index I (0.49), high-high clusters by local Moran's, hotspot by Getis-Ord-Gi* (P < 0.05), point pattern analysis by nearest neighbor ratio and kernel density estimation. The relative risk of the significant cluster was obtained as 1.60 (95% confidence interval: 1.03-1.84) by SaTScan analysis. Conclusion: This study identified spatial variations in the pattern of TC cases with significant clusters near the coastal region of Thiruvananthapuram. This would help to pinpoint the high-risk geographical areas of TC and for more effective cancer control programs.

Robotic right live donor hepatectomy (r-LDRH) has been reported with reduced morbidity compared to open donor right hepatectomy (o-LDRH) in few recent series. Nevertheless, its routine use is debated. We present a large series comparing pure r-LDRH with o-LDRH. Consecutive r-LDRH performed from June 2018 to June 2020 (n = 102) were compared with consecutive donors undergoing o-LDRH (n = 152) from February 2016 to February 2018, a period when r-LDRH was not available at this center. Propensity score matched (PSM) analysis of 89 case-control pairs was additionally performed. Primary endpoints were length of high dependency unit (HDU) and hospital stay and Clavien-Dindo graded complications among donors. Although r-LDRH took longer to perform (540 vs. 462 min, P < .001), the postoperative peak transaminases levels (P < .001), the length of HDU (3 vs. 4 days, P < .001), and hospital stay (8 vs. 9 days, P < .001) were lower in in donors undergoing r-LDRH. Clavien-Dindo graded complications were similar (16.67% in r-LDRH and 13.16% in o-LDRH). The rates of early allograft dysfunction (1.6% vs. 3.3%), bile leak (14.7% vs. 10.7%), and 1-year mortality (13.7% vs. 11.8%) were comparable between r-LDRH and o-LDRH recipients. PSM analysis yielded similar results between the groups. These data support the safety and feasibility of r-LDRH in select donors.

Background: Cancer survival data from Population Based Cancer Registries (PBCR) reflect the average outcome of patients in the population, which is critical for cancer control efforts. Despite decreasing incidence rates, cervical cancer is the second most common female cancer in India, accounting for 10% of all female cancers. The objective of the study is to estimate the five-year survival of patients with cervical cancer diagnosed between 2012 and 2015 from the PBCRs in India. Methods: A single primary incidence of cervical cancer cases of 11 PBCRs (2012-2015) was followed till June 30, 2021 (n = 5591). Active follow-ups were conducted through hospital visits, telephone calls, home or field visits, and public databases. Five-year Observed Survival (OS) and Age Standardised Relative Survival (ASRS) was calculated. OS was measured by age and clinical extent of disease for cervical cancers. Findings: The five-year ASRS (95% CI) of cervical cancer was 51.7% (50.2%-53.3%). Ahmedabad urban (61.5%; 57.4%-65.4%) had a higher survival followed by Thiruvananthapuram (58.8%; 53.1%-64.3%) and Kollam (56.1%; 50.7%-61.3%). Tripura had the lowest overall survival rate (31.6%; 27.2%-36.1%). The five-year OS% for pooled PBCRs was 65.9%, 53.5%, and 18.0% for localised, regional, and distant metastasis, respectively. Interpretation: We observed a wide variation in cervical cancer survival within India. The findings of this study would help the policymakers to identify and address inequities in the health system. We re-emphasise the importance of awareness, early detection, and increase the improvement of the health care system. Funding: The National Cancer Registry Programme is funded through intra-mural funding by Indian Council of Medical Research, Department of Health Research, India, Ministry of Health & Family Welfare.
RESUMO
Malu RafiObjectives This study was undertaken to evaluate the characteristics and treatment outcomes of patients with adenoid cystic carcinomas of the head and neck region treated at a tertiary cancer center in south India. Materials and Methods This was a retrospective study done on patients treated at the institute between 2004 and 2011. Clinicopathological details and treatment outcomes were captured from the treatment records to estimate the treatment outcomes and factors affecting them. Results There were a total of 140 patients with mean age of presentation of 46 years and a median follow-up of 65 months. The most common single site of presentation was the oral cavity. One-hundred eighteen patients (84.3%) underwent primary surgical resection in which 38% had negative surgical margins. Ninety-nine patients were given adjuvant radiotherapy and 18 patients received radical radiotherapy, mostly for surgically inaccessible and inoperable tumors. Median time to recurrence and distant metastasis was 37 and 34 months, respectively. The overall survival and disease-free survival estimate using the Kaplan-Meier method were 92.3 and 71.9%, respectively, at 5 years. Surgical removal of the primary tumor and the nodal stage had the most significant impact on the overall survival outcomes of these patients. Conclusion Surgery remains the most impactful treatment modality in the management of these rare epithelial tumors. The use of adjuvant radiotherapy may help to tackle the issues of perineural spread and inadequate surgical margins in technically difficult sites. Radical radiotherapy also has impressive response rates.
RESUMO
Oral and lip cancer is the most common type of cancer among males in India. Early stage tumours of the lip (stages I and II) are treated with single modality treatment, using either radiotherapy [external beam radiotherapy (EBRT) or brachytherapy] or surgery. Locally advanced tumours (stages III and IVa) are treated with surgery followed by adjuvant treatment. The aim of the present study was to retrospectively evaluate the clinical profile and treatment outcomes of patients with squamous cell carcinoma of the lip who were treated with radical intent at the Regional Cancer Centre (Thiruvananthapuram, India). For this purpose, a total of 120 patients treated with radical radiotherapy (brachytherapy or EBRT) or surgery with or without adjuvant treatment between January 2010 and December 2016 were eligible for the analysis. Kaplan-Meier analysis was used to generate the survival outcomes. Univariate and multivariate analyses were performed to determine the impact of various patient- and tumour-related factors and treatment modality on outcomes. At a median follow-up time of 67.6 months, the disease-free survival (DFS) and overall survival (OS) rates at 4 years for the entire cohort were 69.1 and 86.7%, respectively. The 4-year OS rates for patients with stage I, II, III and IV disease were 88.9, 95.2, 86.8 and 75.3%, respectively, and the DFS rates were 83.6, 69.5, 78.8 and 42.9%, respectively. Primary tumour (P=0.025), nodal (P=0.005) and composite clinical (P=0.006) stage were found to be significant factors affecting DFS rates in the univariate analysis. However, only the nodal stage (P=0.005) was found to be a significant factor affecting DFS rates in the multivariate analysis. On the whole, the present study demonstrates that the outcomes of patients with lip carcinoma are favourable when treated at the early stages, and the results from this series are in line with those already published.
RESUMO
BACKGROUND: Oral diseases like periodontitis and mucositis often require home care using topical agents in the form of mouthwashes. Many herbal mouthwashes are found to be beneficial; however lack proper scientific evidence to support their use. OBJECTIVES: Study 1 evaluated clinical efficacy of herbal mouthwash in the management of chronic periodontitis in comparison with chlorhexidine mouthwash. Study 2 aimed at assessment of herbal mouthwash in patients of radiation-induced mucosititis. METHODS: The novel herbal mouthwash used in the present study wa prepared from extracts of five plants namely Emblica Officinalis, Terminalia chebula, Terminalia bellerica, Glycyrrhiza glabra, and Azadirachta indica. 50 periodontitis patients were randomly allocated to two groups. As per allocation, they were instructed to use either herbal mouthwash or chlorhexidine mouthwash twice daily for two weeks after nonsurgical periodontal therapy. Similarly, patients with radiation-induced mucositis were randomly given herbal mouthwash and soda saline mouthwash. Intergroup and intragroup comparisons of continuous variables were conducted using paired and unpaired t-tests. Categorical variables were compared using the chi-square test. RESULTS: Significant reductions in gingival bleeding, plaque accumulation, and pocket depth were noticed in periodontitis patients in both groups. Patients reported acceptable taste, freshness, and satisfaction after the use of herbal mouthwash. The herbal mouthwash group noticed a significant reduction in the severity of radiation-induced mucositis and analgesic requirements. The intensity of pain, dryness of mouth, oral hygiene, and need for the use of antibiotic and antifungal during radiotherapy was not significant among the groups. CONCLUSION: The results of this preliminary clinical trial support the use of the tested herbal formulation mouthwash as an adjunct in the treatment of periodontitis as well as radiation-induced mucositis. CLINICAL TRIAL REGISTRATION NUMBER: For Study 1: CTRI/2019/10/021574, Study 2: CTRI/2020/04/024851.
RESUMO
Introduction: Oral cancer is a major public health concern in India. Both conventional and altered fractionation radiotherapy schedules have been used in curative treatment of oral cancer. This study aimed to retrospectively evaluate the clinical profile and treatment outcomes of patients with carcinoma buccal mucosa who underwent treatment with definitive hypofractionated accelerated radiotherapy. Methods: A total of 517 patients treated from January 2011 to December 2016 were eligible for the analysis. All patients were treated with definitive hypofractionated accelerated radiotherapy schedule of 5,250 cGy in 15 fractions over 3 weeks. Survival estimates were generated using the Kaplan-Meier method. Results: At a median follow-up of 77.4 months, 473 (91.5%) patients attained complete remission with radiation therapy. The 5-year disease-free survival (DFS) and overall survival (OS) rates were 69% and 80.5%, respectively. The 5-year OS for stage I, II, III and IVa tumours was 80.3%, 84.4%, 81.4% and 73.7%, respectively, and the DFS was 75.7%, 73.2%, 69.6% and 60.2%, respectively. Age >50 years was found to be a significant factor affecting DFS (P = 0.026) and OS (P = 0.048) in multivariate analysis. Fifty-three (10.3%) patients developed osteoradionecrosis of the mandible. Conclusion: Excellent outcome could be achieved in less-aggressive, low-volume carcinoma of the buccal mucosa with radical accelerated hypofractionated radiotherapy. A radiotherapy schedule over a 3-week period is useful in high-volume centres.
RESUMO
Background: Epstein-Barr virus (EBV) DNA quantification in nasopharyngeal cancer (NPC) is an indicator of the tumour burden, stage and survival. Although EBV dynamics in endemic regions has been extensively studied and reported, the data from non-endemic regions is sparse. This study attempts to investigate the EBV dynamics in NPC patients from a non-endemic region and also to identify the factors impacting the outcomes. Materials and methods: This was a prospective observational study conducted at a tertiary care centre in South India and enrolled patients with non-metastatic, biopsy proven NPC, who were suitable for radical chemo-radiotherapy with or without induction chemotherapy. Two blood samples, one prior to initiation of any anticancer treatment, and second at 6 weeks post treatment, were collected to quantify EBV DNA using real-time quantitative polymerase chain reaction. Antibodies against EBV viral capsid antigen (EBV VCA IgM), EBV Early Antigen (EBV EA IgG) and EBV Nuclear Antigen (EBV EBNA IgG) were also measured in the sample. The impact of EBV dynamics on the outcomes was then analysed. Results: The study included a total of 35 patients. Thirty-three had identifiable EBV DNA (94.3%) and a histological diagnosis of non-keratinising undifferentiated type of squamous cell carcinoma. There was no correlation between the EBV DNA and anti-EBV antibodies. There was a significant association between composite stage and pre-treatment DNA titre (p = 0.030). The mean EBV DNA titre was lower for patients with no clinically demonstrable disease at last follow-up and the reduction in EBV DNA titres was significant (p = 0.020) for those patients who remained disease free. Conclusion: Plasma EBV DNA is an accurate and reliable biomarker for NPC for WHO type 2 and 3 tumours even in non-endemic regions.
RESUMO
INTRODUCTION: The purpose of this study is to assess the impact of revision surgery, after unplanned excision, on oncological outcome and surgical morbidity in soft tissue sarcomas and also to assess the relation between margin status and oncologic outcome. MATERIALS AND METHODS: We undertook a retrospective analysis of prospectively maintained database of 153 patients with peripheral soft tissue sarcomas treated in our institute from 2006-2010. RESULTS: Postoperatively, 111(72.5%) patients had negative margins, 20(13.1%) had close margins and 22(14.4%) had planned positive margins. Local recurrence rate was 19.8% in patients with negative margins and 28.6% for patients with close or positive margins (p= 0.007). There was no statistically significant difference in rates of distant metastases (18.9% vs 21.4%, p value 0.56) and five-year overall survival (82.5% Vs 79.8%, p value 0.41) between margin negative and close/positive groups. The five-year overall survival rates were 80.4 vs 77.8% (p =0.42) and five-year disease-free survival rates were 72.4% vs 70.2% (p=0.3), in the revision surgery group and primary surgery group respectively. CONCLUSION: Margin status after excision of soft tissue sarcoma is not a direct predictor for overall survival or distant metastasis. Revision surgery after an unplanned excision does not carry worse survival compared to primary surgery group.

CONTEXT: Differentiating NSCLC as either adeno or squamous type and identification of Epidermal Growth Factor Receptor (EGFR) mutations is clinically relevant for lung cancer patients for selecting treatment. Thyroid transcription factor-1 (TTF-1) and p63 were demonstrated as useful markers for histologic typing of lung cancer. Mutation and overexpression of EGFR has been reported in a subset of non-small cell lung cancers. If these markers can be validated for the differential diagnosis of adenocarcinoma in a sputum sample itself, it will be highly beneficial for lung cancer patients. AIMS: To evaluate whether immunocytochemical expression of TTF-1, p63, and EGFR proteins in sputum samples can be used for differential diagnosis of lung adenocarcinoma by comparing with that of the corresponding tissue samples. SETTINGS AND DESIGN: Ninety sputum samples and matched tissue samples were used for the study. SUBJECTS AND METHODS: Monolayered smears and cell blocks of sputum and the corresponding tissue samples were immunostained with the standard ABC method. The expression patterns of these markers were analyzed statistically and compared with clinic-pathological parameters. STATISTICAL ANALYSIS USED: Chi-square test and paired t-test. RESULTS: The p63 protein had a positive expression in 73.9% of SCC whereas TTF1 had positive expression in 75.8% of ADC. The EGFR expression was positive in 27 cases of adenocarcinoma, 21 cases of SCC and 19 cases of NSCLC. CONCLUSIONS: Immunocytochemistry of the aforementioned antibodies in sputum samples can be used as supplementary evidence for the subtyping of NSCLC.
RESUMO
PURPOSE: Lower socioeconomic status is associated with more advanced cancer at the time of cancer diagnosis. It is unknown whether this leads to inferior survival in low- and middle-income countries. Here, we explore the association between educational level and survival in South India. METHODS: The Trivandrum Cancer Registry (3.3 million population) was used to identify all cases of breast and cervical cancer (women) and oral cavity (OC) and lung cancer (men) diagnosed during 2012-2014. Educational level was classified as illiterate/primary school, middle school, and secondary school and above. Survival was measured from date of diagnosis using the Kaplan-Meier method. Cox proportional hazards regression modeling was used to describe the associations among education, stage of cancer at diagnosis, and survival. RESULTS: The study population included 3,640 patients with breast (n = 1,727), cervical (n = 425), OC (n = 702), and lung (n = 786) cancer. Educational level was 27%, 23%, and 32% for illiterate/primary, middle, and secondary school and above, respectively. The 5-year survival rate for breast cancer was 59%, 68%, and 73% (P = .001); for cervical cancer, 51%, 52%, and 60% (P = .146); and for OC cancer, 42%, 35%, and 48% (P = .012) for illiterate/primary, middle school, and secondary school and above, respectively. The survival gradient across social groups was substantially attenuated when stage was added to the multivariable model. There was no observed difference in survival across educational groups for lung cancer (2%, 4%, and 3%; P = .224). CONCLUSION: Data from this population-based study in South India demonstrate that patients from a lower educational background have inferior survival and that this is at least partially explained by having more advanced disease at the time of diagnosis. Public health efforts are needed to facilitate timely diagnosis and reduce disparities in cancer outcomes.

CONTEXT: Despite sputum cytology being accepted as a simple and noninvasive diagnostic method for lung cancer, the clinical usefulness of sputum for evaluation of prognosis is yet to be explored. Validation of some of the markers in sputum for prognosis prediction will be highly useful for selective therapy. AIMS: This study was aimed to evaluate a reliable panel of immunocytochemical markers for their significance to predict survival. MATERIALS AND METHODS: We have analyzed the expression of p53, p16, galectin-3, and epidermal growth factor receptor (EGFR) proteins in sputum samples processed in a mucolytic agent/cellblock and compared the same with that of the corresponding tissue samples. RESULTS: Overexpression of p16 and EGFR was found to have a better survival benefit, whereas positive p53 and galectin-3 expressions had shorter period of survival. Expression patterns of all these four proteins were more or less similar in smears, cellblocks of sputum, and tissue samples except for slight changes in staining intensity which was not found to be statistically significant. No significant difference was found in the association of these proteins with survival pattern between sputum and tissue samples. CONCLUSION: This is the first report of immunocytochemistry of a panel of markers on cells exfoliated in sputum samples which suggests that analysis of immunocytochemical markers in sputum samples can be attempted as a cost-effective and reliable predictor of prognosis and survival. Accumulation of mutated p53, overexpression of galectin-3, and lower expression of p16 and EGFR proteins were found to predict poor prognosis for lung cancer.
RESUMO
BACKGROUND & OBJECTIVES: An assessment of transition of cancer in India during the past 30 years, according to changes in demographic and epidemiologic risk factors was undertaken. MATERIALS & METHODS: Cancer registry data (http://www.ncdirindia.org), (population coverage <10%), was compared with transition in life-expectancy and prevalence on smoking, alcohol and obesity. We fitted linear regression to the natural logarithm of the estimated incidence rates of various cancer registries in India. RESULTS: Burden of cancer in India increased from 0.6 million in 1991 to 1.4 million in 2015. Among males, common cancers are lung (12.0%), mouth (11.4%), prostate (7.0%), and tongue (7.0%) and among females, they are breast (21.0%), cervix-uteri (12.1%), ovary (6.9%), and lung (4.9%) in 2012. Increased life-expectancy and population growth as well as increased use of alcohol and increased prevalence of overweight/obesity reflected an increase in all cancers in both genders except a reduction in infection-related cancers such as cervix-uteri and tobacco-related cancers such as pharynx (excludes nasopharynx) and oesophagus. INTERPRETATION & CONCLUSION: Transition in demographics and epidemiologic risk factors, reflected an increase in all cancers in both genders except a reduction in a few cancers. The increasing incidence of cancer and its associated factors demands a planned approach to reduce its burden. The burden assessment needs to be strengthened by increasing the population coverage of cancer registries. Continued effort for tobacco prevention and public health efforts for reducing obesity and alcohol consumption are needed to reduce the cancer burden.

PURPOSE: Lower socioeconomic status is associated with inferior cancer survival in high-income countries, but whether this applies to low- and middle-income countries is not well described. Here, we use a population-based cancer registry to explore the association between educational level and stage of cancer at diagnosis in South India. METHODS: We used the Trivandrum District population-based cancer registry to identify all cases of breast and cervical cancer (women) and oral cavity (OC) and lung cancer (men) who were diagnosed from 2012 to 2014. Educational status-classified as illiterate/primary school, middle school, or secondary school or higher-was the primary exposure of interest. Primary outcome was the proportion of patients with advanced stage disease at diagnosis defined as stage III and IV (breast, cervix, or OC) or regional/metastatic (lung). RESULTS: The study population included 4,547 patients with breast (n = 2,283), cervix (n = 481), OC (n = 797), and lung (n = 986) cancer. Educational status was 22%, 19%, and 26% for illiterate/primary, middle, and secondary school or higher, respectively. Educational status was missing for 33% of patients. The proportion of all patients with advanced stage disease was 37% (breast), 39% (cervix), 67% (OC), and 88% (lung). Patients with illiterate/primary school educational status were considerably more likely to have advanced breast cancer (50% v 39% v 36%; P < .001), cervix cancer (46% v 43% v 24%; P = .002), and OC cancer (77% v 76% v 59%; P < .001) compared with patients with higher educational levels. The proportion of patients with advanced lung cancer did not vary across educational levels (89% v 84% v 88%; P = .350). CONCLUSION: A substantial proportion of patients in South India have advanced cancer at the time of diagnosis. This is particularly true among those with the lowest levels of education. Future health awareness and preventive interventions must target less-educated communities to reduce delays in seeking medical care for cancer.

INTRODUCTION: Lesions of the thyroid gland composed of Hurthle cells constitute a wide spectrum of pathological entities ranging from benign hyperplastic nodules with Hurthle cell metaplasia at one end to malignancies like Hurthle cell carcinomas. The cytological distinction of these entities is not only diagnostically challenging but are also critical since they influence treatment decisions. AIM: To critically analyze the cytomorphology of cases of Hurthle cell lesions in FNACs and to characterize cytological features shown to be statistically signific ant in predicting Hurthle cell neoplasm (HCN). METHODS: During the period from January 2014 to August 2015, 1667 cases of thyroid FNAs were done at our centre, of which 54cases,showed a predominance of hurthle cells, i.e. more than or equal to 50% hurthle cells (≥=50%).These cases were included in the study and were critically reviewed for 9 cytomorphologic features which included cellularity, architecture, and percentage of Hurthle cells, background colloid, chronic inflammation, nucleoli, intranuclear cytoplasmic inclusions (INCI), nuclear grooves and transgressing blood vessels (TBV). The results were evaluated by using univariate and stepwise logistic regression (SLR) analysis; statistical significance was achieved at P-value < 0.05. RESULTS: Out of the 9 parameters studied, the cytological features shown to be statistically significant in predicting HCN and distinguishing them from benign hurthle cell lesions(BHCLs) were increased cellularity, non-macro follicular architecture, >90% Hurthle cells, absence of background colloid and absence of chronic inflammation.

BACKGROUND: Concurrent chemoradiation with 3 weekly cisplatin (100 mg/m2) is the standard of care for locally advanced head and neck cancer. However, this regimen has been shown to be associated with lesser compliance and higher toxicities. Hence, there is a need to explore alternative concurrent cisplatin regimens. OBJECTIVES: The objective of this study was to compare the efficacy and toxicities of 3 weekly cisplatin (100 mg/m2) with weekly cisplatin (40 mg/m2) concurrently with radiation in patients with locally advanced head and neck cancer. PATIENTS AND METHODS: This phase IIb trial randomized 56 patients with Stage III and IV squamous cell carcinoma of oropharynx, hypopharynx, and larynx to Arm A or Arm B. Arm A received cisplatin 100 mg/m2 3 weekly and Arm B received cisplatin 40 mg/m2 weekly concurrently with radiation. The primary end point was disease-free survival (DFS) and secondary end points were overall survival (OS) and acute toxicity. DFS and OS were estimated using Kaplan-Meier method, and log-rank test was used to assess the difference in these distributions with respect to treatment. RESULTS: The 2-year DFS in Arm A and Arm B was 64.5% and 52.8%, respectively (P = 0.67). The OS at 2 years was 71% and 61.1% in Arm A and Arm B, respectively (P = 0.61). There were no significant differences in acute hematological, renal, or mucosal toxicities between the two arms. CONCLUSION: This study showed a nonsignificant improvement in DFS and OS in the 3 weekly cisplatin arm over the weekly arm with comparable toxicities. The trial is registered with Clinical Trial Registry of India (CTRI registration number: CTRI/2013/05/003703, URL-http://ctri.nic.in).
RESUMO
BACKGROUND: Increasing breast cancer (BC) incidence rates have been reported from India; causal factors for this increased incidence are not understood and diagnosis is mostly in advanced stages. Trivandrum exhibits the highest BC incidence rates in India. This study aimed to estimate trends in incidence by age from 2005- 2014, to predict rates through 2020 and to assess the stage at diagnosis of BC in Trivandrum. MATERIALS AND METHODS: BC cases were obtained from the Population Based Cancer Registry, Trivandrum. Distribution of stage at diagnosis and incidence rates of BC [Age-specific (ASpR), crude (CR) and age-standardized (ASR)] are described and employed with a joinpoint regression model to estimate average annual percent changes (AAPC) and a Bayesian model to estimate predictive rates. RESULTS: BC accounts for 31% (2681/8737) of all female cancers in Trivandrum. Thirty-five percent (944/2681) are <50 years of age and only 9% present with stage I disease. Average age increased from 53 to 56.4 years (p=0.0001), CR (per 105 women) increased from 39 (ASR: 35.2) to 55.4 (ASR: 43.4), AAPC for CR was 5.0 (p=0.001) and ASR was 3.1 (p=0.001). Rates increased from 50 years. Predicted ASpR is 174 in 50-59 years, 231 in > 60 years and overall CR is 80 (ASR: 57) for 2019- 20. CONCLUSIONS: BC, mostly diagnosed in advanced stages, is rising rapidly in South India with large increases likely in the future; particularly among post-menopausal women. This increase might be due to aging and/or changes in lifestyle factors. Reasons for the increased incidence and late stage diagnosis need to be studied.

OBJECTIVE: Cervical cancer is the one of most common cancer in India, and a significant proportion of patients do not complete the prescribed courses of treatment and post therapy surveillance, due to deficiencies in treatment availability, accessibility, affordability and other socio-demographic factors. MATERIALS AND METHODS: Cervical cancer patient data for the year 2006-2007 were collected during June-August, 2008 from the Regional Cancer Centre (RCC), Thiruvananthapuram, Kerala, India and investigated for socio-economic, demographic and disease (SEDD) related factors impacting patients to drop-out during treatment and patients to loss to follow-up (LFU) post therapy. Odds ratio (OR) for drop-out and LFU and their 95% confidence intervals (CIs) according to SEDD factors were estimated through logistic regression model. RESULTS: Among a total of 784 patients, 94 (12%) did not complete the initially planned treatment and among 690 cases who had completed the initially planned treatment, 34% were lost to follow up (LFU). In the multivariate analysis, higher chances of LFU for older patients (OR=1.8; 95% CI: 1.1-3.1), widowed/divorced/separated/unmarried (OR=1.5; 95%CI: 1.0-2.1), middle school education (OR=1.8; 95% CI: 1.0-3.1), poorer performance status (OR=2.4; 95% CI: 1.2-5.0) and in higher stages (OR= 4.6; 95% CI: 2.1- 10.3). Higher chances of drop-outs were noted for patients with medium income (OR=2.0; 95% CI: 1.0-4.1), higher stages (OR=4.8; 95% CI: 1.9-12.2) and ischemic heart disease (OR=3.4; 95% CI: 1.1-10.9). CONCLUSION: Drop-out rates are associated with disease related factors and patients in the LFU group were affected mainly by SEDD factors. Physicians should be aware of patients' different needs in these two different phases, thus improving the retention rate in the near future of cancer treatment.
