Clinical Outcomes and Patterns of Failure After Intensity-Modulated Radiotherapy with Simultaneous Integrated Boost for Nasopharyngeal Carcinoma: A Single Institutional Review.

Unlabelled: With conformal radiotherapy techniques, acute and late toxicities can be reduced because of significantly better dose conformity and reduced doses to normal tissue. With Intensity Modulated Radiation Therapy (IMRT) further dose escalation is possible. To evaluate clinical outcomes and patterns of failure after IMRT-SIB (Simultaneous integrated boost)/(Volumetric modulated arc therapy) VMAT technique in nasopharyngeal cancer patients.

Role of Proton Beam Therapy in Hepatic Oligometastasis: Review of Evidence.

Hepatic oligometastasis (hOMC) incidence varies from 10-40% in the literature. While the old standard for local treatment was surgical resection, options like TACE, TARE, SBRT with photons and off late protons have come to the fore. The proton beam therapy (PBT) use has gradually started to get adopted in all regions worldwide with increasingly better availability and ever-reducing costs.

The current role of adjuvant radiotherapy in management of medullary thyroid carcinoma: A single institute analysis.

Objectives: Medullary thyroid carcinoma (MTC) accounts for only about 5% of total thyroid cancers. It usually presents as an advanced disease carrying a poor prognosis than well-differentiated thyroid cancers. While the treatment of choice is surgery, the role of adjuvant radiotherapy is still unclear.

Dosimetric Comparision of Coplanar versus Noncoplanar Volumetric Modulated Arc Therapy for Treatment of Bilateral Breast Cancers.

Introduction: The purpose of this study was to compare the dosimetric parameters of volumetric modulated arc therapy (VMAT) treatment plans using coplanar and noncoplanar beams in patients with bilateral breast cancer/s (BBCs) in terms of organ at risk sparing and target volume coverage. The hypothesis was to test whether VMAT with noncoplanar beams can result in lesser dose delivery to critical organs such as heart and lung, which will result in lesser overall toxicity.

Materials And Methods: Data of nine BBC cases treated at our hospital were retrieved.

Treatment Pattern and Outcomes in Verrucous Carcinoma of Oral Cavity: A Single Institutional Retrospective Analysis from a Tertiary Cancer Center and Review of Literature.

Verrucous carcinoma (VC) is a locally invasive uncommon histopathological variant of oral squamous cell cancer. There is paucity of literature regarding control rates in these cases. We intend to report the outcomes in terms of administered treatment and control rates.

Long term outcome and late toxicity Of SIB-IMRT in definitive management of head and neck cancers in patients not suitable for chemo-radiotherapy.

Objective: To evaluate efficacy and late toxicity of intensity-modulated radiotherapy with simultaneous integrated boost (IMRT-SIB) in definitive management of head-and-neck cancers.

Methods: In this prospective interventional study, histological proven squamous cell carcinoma of oropharynx, hypopharynx, or larynx with stage T1-3 N0-3 M0 who were not candidates for concurrent chemotherapy were treated with IMRT-SIB with radical intent. Doses prescribed for IMRT-SIB to meet the clinical needs of nodal volumes were either SIB-66 schedule 66 Gray (Gy) prescribed to high risk (HR) planned target volume (PTV), 60 (Gy) to intermediate risk (IR) PTV and 54 Gy to low risk (LR) PTV in 30 fractions or SIB-70 schedule 70 Gy to PTV-HR, 59.

Prospective evaluation of definitive chemoradiotherapy with volumetric modulated arc therapy in patients with muscle invasive carcinoma of urinary bladder.

Introduction: Concurrent chemoradiotherapy (CTRT) remains one of the treatment options in patients with muscle invasive bladder cancer (MIBC) unwilling/unsuitable for radical surgery. We evaluated the role of volumetric modulated arc therapy (VMAT) in MIBC patients treated with definitive CTRT.

Material And Methods: 25 patients of histologically proven transitional cell MIBC (T2-T4a, N0, M0) unwilling/unsuitable for radical surgery (after maximal transurethral resection of bladder tumour) were recruited in this prospective study.

Patterns of failure and clinical outcomes of post-operative buccal mucosa cancers treated with adjuvant ipsilateral radiotherapy.

Purpose: Adjuvant radiotherapy (RT) in buccal mucosa cancers is guided by histopathological factors. The decision to treat ipsilateral or bilateral draining lymph node is on physician discretion and guidelines do not have a defined indication regarding this. We aimed to analyze the failure patterns and survival in buccal mucosa cancers treated with adjuvant ipsilateral RT.

Correlation of Molecular Markers in High Grade Gliomas with Response to Chemo-Radiation.

Background: The standard of care in high grade glioma (HGG) is maximal safe surgical resection followed by adjuvant radiotherapy (RT) with/without chemotherapy. For anaplastic gliomas, studies have shown use of procarbazine, lomustine, vincristine (PCV) improves overall survival (OS) and progression free survival (PFS). Currently, there is substantial evidence that molecular markers strongly predict prognosis and response to treatment.

Evaluation of purely accelerated six fractions per week radiotherapy in postoperative oral cavity squamous cell carcinoma.

Objectives: Randomized controlled trials have shown improved loco-regional control (LRC) and disease-free survival (DFS) by modest acceleration using six fractions per-week radiotherapy (RT) as compared to conventional fractionation in patients of head and neck squamous cell carcinoma. We aimed to evaluate the role of pure modestly accelerated fractionated radiotherapy (PM-ART) using six fractions per-week in patients of postoperative oral cavity squamous cell carcinoma (OCSCC).

Materials And Methods: Between May 2015 and July 2016, 40 OCSCC patients with ≥ 1 indication of RT were treated with adjuvant PM-ART, 60 Gray in 30 fractions over 5 weeks by three-dimensional conformal technique on a linear accelerator with a sixth 2 Gray fraction on Saturday using same fields.

Primary amelanotic malignant melanoma of cervix masquerading as squamous cell carcinoma presenting with extensive metastases.

Amelanotic melanoma of cervix is a rare and aggressive neoplasm and only few cases have been reported in the literature. We report a rare case of an amelanotic melanoma of the uterine cervix with extensive metastases and multiple subcutaneous nodules. Due to the unusual site and amelanotic nature of the lesion, chances of misdiagnosis are high and immunohistochemical markers for melanoma help establish the diagnosis.
