In a low-resource setting, a single round of HPV testing was associated with a significant reduction in the numbers of advanced cervical cancers and deaths from cervical cancer.

Purpose Chemoradiation with cisplatin 100 mg/m given once every 3 weeks is the standard of care in locally advanced head and neck squamous cell cancer (LAHNSCC). Increasingly, low-dose once-a-week cisplatin is substituted because of perceived lower toxicity and convenience. However, there is no level 1 evidence of comparable efficacy to cisplatin once every 3 weeks. Patients and Methods In this phase III randomized trial, we assessed the noninferiority of cisplatin 30 mg/m given once a week compared with cisplatin 100 mg/m given once every 3 weeks, both administered concurrently with curative intent radiotherapy in patients with LAHNSCC. The primary end point was locoregional control (LRC); secondary end points included toxicity, compliance, response, progression-free survival, and overall survival. Results Between 2013 and 2017, we randomly assigned 300 patients, 150 to each arm. Two hundred seventy-nine patients (93%) received chemoradiotherapy in the adjuvant setting. At a median follow-up of 22 months, the estimated cumulative 2-year LRC rate was 58.5% in the once-a-week arm and 73.1% in the once-every-3-weeks arm, leading to an absolute difference of 14.6% (95% CI, 5.7% to 23.5%); P = .014; hazard ratio (HR), 1.76 (95% CI, 1.11 to 2.79). Acute toxicities of grade 3 or higher occurred in 71.6% of patients in the once-a-week arm and in 84.6% of patients in the once-every-3-weeks arm ( P = .006). Estimated median progression-free survival in the once-a-week arm was 17.7 months (95% CI, 0.42 to 35.05 months) and in the once-every-3-weeks arm, 28.6 months (95% CI, 15.90 to 41.30 months); HR, 1.24 (95% CI, 0.89 to 1.73); P = .21. Estimated median overall survival in the once-a-week arm was 39.5 months and was not reached in the once-every-3-weeks arm (HR, 1.14 [95% CI, 0.79 to 1.65]; P = .48). Conclusion Once-every-3-weeks cisplatin at 100 mg/m resulted in superior LRC, albeit with more toxicity, than did once-a-week cisplatin at 30 mg/m, and should remain the preferred chemoradiotherapy regimen for LAHNSCC in the adjuvant setting.

Sarcomatoid carcinomas are biphasic tumors proven to be monoclonal dedifferentiated forms of conventional squamous carcinomas. This study evaluates their clinicopathologic characteristics in head and neck mucosal sites and the problems in distinguishing them from other spindle cell tumors. A total of 103 cases with a confirmed diagnosis of sarcomatoid carcinoma accessioned in the pathology department of a tertiary referral cancer centre over a period of 7 years (2004)(2005)(2006)(2007)(2008)(2009)(2010) were studied. An algorithm used for their diagnosis is presented. Ages of the patients were 22-90 years (median 53 years), and male:female ratio was 3.7:1. Site distribution was oral cavity (n = 65, 63.1%), larynx (18, 17.5%), oropharynx/hypopharynx (12, 10.7%), maxilla (6, 5.8%) and metastatic nodes (2, 1.9%). A large number of patients (95%) presented with a mass lesion of less than 1 year duration. Histopathologically, epithelial differentiation was evident on morphology in 48 (46.6%) cases, only on IHC in 34 (33%) cases, and in 21 (20.4%) no epithelial differentiation was seen. Typically, tumors were polypoidal (92, 89.3%) and ulcerated (95, 92.2%) with cells arranged predominantly in fascicles (59, 57.3%) or storiform pattern (17, 16.5%) amidst collagenous (50, 48.5%) or myxoid matrix (35, 34%). Anaplasia (2?/3?) and mitosis[10 per 10 HPF were noted in 96 (93.2%) cases. IHC was done in 82 cases; 55 (66.7%) showed positivity for epithelial markers with aberrant expression of mesenchymal markers in 43 (41.7%). Diagnosis of sarcomatoid squamous carcinoma is challenging because of overlapping histopathological features with other spindle cell tumors. Understanding their clinicopathologic characteristics facilitates their diagnosis and appropriate clinical management.

The impact of screening by visual inspection with acetic acid (VIA), cytology or HPV testing on cervical cancer incidence and mortality is investigated in a cluster randomized controlled trial in India. We report findings after the screening phase, when 52 clusters, with a total of 142,701 women aged 30-59 years in Osmanabad District, India, were randomized into 4 arms for a single round of screening by trained midwives with either VIA, cytology or HPV testing as well as a control group. All laboratory tests were done locally. Test-positive women underwent investigations (colposcopy=biopsy) and treatment in the base hospital. Data on participation, test positivity, positive predictive value and detection rates of cervical neoplasia were analyzed using cluster design methodology. Of the eligible women, 72-74% were screened. Test positivity rates were 14.0% for VIA, 7.0% for cytology and 10.3% for HPV. The detection rate of high-grade lesions was similar in all intervention arms (0.7% for VIA, 1.0% for cytology and 0.9% for HPV testing) (p 5 0.06, Mann-Whitney test). While the detection rate for VIA dropped to 0.5% with declining test positivity during the course of the study, it remained constant for cytology and HPV testing. Over 85% of women with high-grade lesions received treatment. Our results show that a high level of participation and good-quality cytology can be achieved in low-resource settings. VIA is a useful alternative but requires careful monitoring. Detection rates obtained by HPV testing were similar to cytology, despite higher investments.

Its accuracy at detecting cervical neoplasia has been extensively studied and found to be satisfactory. [5][6][7] The role of persistent infection with oncogenic types of HPV in the etiology of cervical cancer has encouraged the evaluation of HPV testing as a screening tool. [8][9][10] The ultimate proof of efficacy of a screening test for cervical neoplasia is its ability to prevent invasive cancer when implemented in a program setting. Whether a screening program using VIA or HPV testing will be followed by a reduction in disease burden and the cost-effectiveness of these alternate approaches based on real program-based information remain to be established. These appro...
