pylori bacteria.

Our study showed a significant presence of H. pylori in histological sections of OSCC, and it seems likely that the presence of H. pylori might be a risk factor for the developing oral lesions such as oral cancer. Early detection and eradication of H. pylori in the oral cavity, especially in high-risk patients, might prevent its harmful consequences.

Recurrent nasopharyngeal carcinoma (NPC) after previous radiation therapy is a significant problem. This study was to determine the potential benefits from re-irradiation by fractionated stereotactic body radiotherapy (FSRT) on survival benefits and effects of severe late toxicities.

Between 2009 and 2018, treatment outcomes were evaluated retrospectively in 26 patients with locally recurrent NPC treated using FSRT with CyberKnife. Five patients who had metastatic disease and one who had second recurrence were excluded from the study, and the remaining 20 patients were analyzed. The median age was 52 years (range, 28-80 years); re-treatment T stage was as follows 6 (30%) - T2, 5 (25%) - T3, and 9 (45%) - T4. The median time from initial RT to recurrence was 22 months (range, 8-159 months). The median re-irradiation FSRT dose was 30 Gy in 5 fractions.

The median follow-up was 44 months; the overall survival (OS), local failure-free survival, and disease progression-free survival rates at 3 years were 89%, 73%, and 53%, respectively. this website All patients were evaluated for response after treatment 9 (45%) had complete, 3 (15%) had partial, and 6 (30%) had no response. Univariate analysis demonstrated that higher cumulative total radiotherapy dose, gross tumor volume, and recurrent time interval were prognostic factors for local failure-free survival. The recurrent time interval was also an independent factor for progression-free survival and OS. The incidence of temporal lobe necrosis and trismus was 10% and 20%, respectively. One patient had Grade 5 toxicity to treatment-related bleeding.

Tumor dose coverage is important for treating recurrent NPC, and treatment-related mortality was vascular in nature. FSRT is a promising treatment modality for recurrent NPC.

Areca nut, a causative factor for oral submucous fibrosis (OSMF), is identified as a Group 1 human carcinogen. Oral squamous cell carcinoma (OSCC) associated with OSMF is now one of the most common malignancies in South and Southeast Asian countries.

The present study was aimed to have clarity whether OSCC associated with OSMF is a pathologically different disease having different prognosis.

The difference between OSCC associated with OSMF and OSCC not associated with OSMF was studied in relation to expression of molecular markers, Ki-67, a proliferative and prognostic marker for OSCC and matrixmetalloproteinase-9 (MMP-9), and alpha smooth muscle actin (α-SMA), markers for invasiveness.

Expression was analyzed immunohistochemically using paraffin-embedded tissues from ten normal oral mucosa (Group I), thirty OSCC associated with OSMF (Group II), and thirty OSCC not associated with OSMF (Group III).

Group II showed OSCC occurring at younger age with more cases of well-differentiated OSCC. It also shoease pathologically and biologically. In-depth analysis of this molecular profiling can help to establish diagnostic, prognostic and therapeutic modalities for this unique malignancy.
Head-and-neck squamous cell carcinomas (HNSCCs) are one of the most common malignancies worldwide. Emerging evidence reveals that tumor-infiltrating lymphocytes (TIL) provide valuable prognostic information in various malignancies, including HNSCC.

The present study aimed to evaluate a simple yet accurate method of counting TILs in HNSCCs. It was also done to determine if there is any correlation between different clinicopathological parameters of HNSCC and TIL counts.

A.

The present study included 81 patients, among which 51 (63%) were male and the rest (30, 37%) were female. The mean age of the patients was 55.3 ± 10.5 years. Most tumors were located in the oral cavity (73, 90.1%). The most common histologic type was moderately differentiated (MD) squamous cell carcinoma (SCC) (50 cases, 61.7%). Stromal TIL score was high in 45 cases (55.6%). In 69 cases (85.2%), the intratumoral TIL level was low. A statistically significant correlation was found between TIL levels (both stromal and intratumoral TIL) and tumor differentiation, pT stage, and lymphovascular invasion. The correlation between intratumoral TIL level, age of patients, and pN stage was also statistically significant.

TIL evaluation is an inexpensive, simple, and reproducible method, which furnishes relevant prognostic data. It has the potential for consideration of its inclusion in routine histopathological reports of HNSCCs.

Radiation-induced mucositis and dermatitis are severe side effects and compromise the health of the head-and-neck cancer patient undergoing treatment. Zinc supplementation during the course of the treatment is shown to have protective effects against both radiation-induced mucositis and dermatitis. The aim of this study was to understand whether the level of serum zinc has an effect on the development of mucositis and dermatitis.

This was noninterventional study where the levels of serum zinc were ascertained before the start of treatment by spectrophotometric methods. The patients were treated every day with no more than one fraction of 2 Gy per day, five times a week without any intended gaps for a planned target dose of 60-70 Gy (6-7 consecutive weeks). The patients were assessed for radiation-induced dermatitis and mucositis in accordance with the standard guidelines. The association between the levels of serum zinc with the development of different grades of mucositis and dermatitis (on the day of deh better effects seen in dermatitis where it was also effective in Grades 2 and 3.
Oral squamous cell carcinoma associated with oral submucous fibrosis (OSCC with OSMF) is clinicopathologically a distinct entity. However, scientific proof in view of assessment of biomarkers of hypoxia and neoangiogenesis to differentiate them are lacking. The expression of hypoxia-inducible factor 1-α (HIF-1α) and CD105 in OSCC with and without OSMF possibly will be explicated along these lines.

This study aims to evaluate the molecular basis of hypoxia and neoangiogenesis in terms of immunohistochemical expression of HIF-1α and CD105 in OSCC with and without OSMF cases.

A retrospective cohort.

The study comprise of 203 histopathologically diagnosed surgically operated cases of OSCC retrieved from the departmental archives. The OSCC cases were subgrouped into two, OSCC with OSMF (Group I) and OSCC without OSMF (Group II). The evaluation of hypoxia and angiogenesis was carried out by immunohistochemical markers, HIF-1α and CD105. MVD is the parameter of angiogenesis expressed by CD105.

Differences in CD105, and HIF-1α immunoreactivity between study groups were done using descriptive statistics using "Kruskal-Wallis test," "Mann-Whitney test." Statistical significance was set at P < 0.05.

On comparison of MVD in Group I and II, statistically significant difference was found in MVD (8.88 ± 3.41, 16.13 ± 5.86, P = 0.0001). The HIF1-α expression was less in Group I (6.85 ± 2.62) as compare to Group II (7.22 ± 3.08) but the difference was statistically nonsignificant (P = 0.35).

The OSCC with OSMF is not only clinicopathologically distinct entity of OSCC but also diverse in its molecular pathogenesis as explicited by distinct expression of HIF-1 α and CD105.

Chemoradiation is the standard of care in locally advanced non-small cell lung cancer (LA-NSCLC). Clinical presentation, disease course, and available treatment options are challenges to overcome. Little is known about the ideal timing and interaction of the two modalities, its relevance in day-to-day decision-making and the treatment outcome.

The study evaluates the demographic profile, treatment pattern, outcome, and radiotherapy (RT) practice and patient care of LA-NSCLC at a tertiary cancer center.

This is a retrospective study from a tertiary cancer centre. Archives of patients of LA-NSCLC treated between June 2016 and June 2018 were included in our study.

Clinical, demographic characteristics, treatment patterns, and outcomes were recorded. RT practice and patient care process including the integration of RT with other specialties, waiting time, and compliance to treatment were documented and analyzed.

Overall survival (OS) and progression-free survival (PFS) were the primary endpoints of the d of the cases of NSCLC present in LA stage and a third are suitable for definitive chemoradiation and only 20% undergo the planned treatment.Curcumin, the key bioactive phytochemical present in turmeric (Curcuma longa L.), is the most studied natural compound in cancer. Preclinical studies (in vitro and in vitro) and clinical trials have demonstrated curcumin's effectiveness as an anti-inflammatory agent. The existing evidence supports that curcumin inhibits the proliferation of many types of cancer cells and can play an important role in cancer therapy. This study analyses the existing evidence in the literature on finalized clinical trials (2010-2020) related to the effect of curcumin and turmeric-derived products that focused on different types of cancers, such as chronic myeloid leukemia, multiple myeloma, prostate, colorectal and pancreatic cancer as well as cancer therapy-related complications, including oral mucositis and radiation dermatitis. Original English language articles and clinical trials published between 2010 and 2020 were searched using mainstream scholarly databases, such as PubMed, ScienceDirect, Google Scholar, and ClinicalTrials.gov. The keywords, such as "curcumin," "turmeric," "cancer," "anti-inflammatory," and "clinical trials," were used in various combinations. A total of 21 clinical trials were selected, reviewed, and included in this study. Sixteen out of 21 clinical trials were associated with the effectiveness of curcumin or turmeric on various types of cancer, and the other five clinical trials were related to the evaluation of the efficacy of curcumin or turmeric in relieving the side effects of cancer chemotherapy and radiotherapy. The emerging data from the clinical trials confirm that curcumin has the potential for cancer prevention and intervention. However, it is not yet clear whether long-term curcumin supplementation has similar benefits.
