Immunotherapy has a specific toxicity profile and many oncologists are facing a new challenge in the form of clinical management of immune-related adverse events (irAEs). Even though most irAEs remain mild in intensity, around 10% of patients treated with anti-PD1/anti-PDL1 drugs will develop severe, sometimes life-threatening, dysimmune toxicities. Skin toxicity is one of the most common irAEs. The irAEs related to skin toxicity can have many different presentations, which includes maculopapular or papulopustular rash, Sweet’s syndrome, follicular or urticarial dermatitis. It typically occurs within 6 weeks from the beginning of the treatment but, due to the mechanism of action of immunotherapic drugs, delayed toxicities are reported.

Methods: The patients were randomly divided into two groups of 30 each. Group I patients were planned for 14.8 Gy in 4 fractions over 2 days every 3 weeks for three cycles. All these patients also received paclitaxel 60 mg/m2 intravenous. Group II patients received 14.8 Gy in 4 fractions over 2 days every 3 weeks for three cycles alone.

Disease status (tumor+node) at the end of treatment in terms of complete response was 36.7% vs. 0% (11/30 and 0/30) in Group I and II. Disease status at 6 months of follow up was noted as follows: complete tumor response in Group I and II was 23.3% (7/30) vs. 10% (3/30) (p=0.012).

The latest reports show that the colorectal cancer is increasing in India at a high rate due to food habits, particularly consuming the foods with high fat content. Chemotherapy has been considered as a potential treatment in the control of a wide range of cancers recently, such as gastrointestinal cancers and so on. The scientists are looking to come up with new drugs to treat cancer by regulating the carcinogenesis with minimal toxicity. Curcumin is a phytochemical extracted from turmeric. It is highly effective product of the rhizomes of Curcuma longa L. (Zingiberaceae). It is also considered as a valuable drug for chemotherapeutic treatments in cancer. In case of animal studies, it has been clearly mentioned that curcumin controls carcinogenesis in various other organs as well as colon. Curcumin exhibits the capability to act as anti-mutagenic, anti-inflammatory drug as well. It has also been confirmed that the P-gp expression regulation is carried out by curcumin by inhibiting the COX-2 expression. Also, it has been clearly stated that curcumin down-regulates NF-kB pathway in various cell lines like Colo 205 colon cancer cell line etc. Multi Drug Resistance (MDR) plays a key role in case of the cancer cells to exhibit the resistance against the cytotoxicity of various chemotherapeutic drugs. This type of characteristics in cancer cells is developed due to low levels of the chemotherapeutic drug accumulated inside the cells during repeated exposure to the drug, showing the over-expression of P-glycoprotein (MDR-1). P-glycoprotein, a transporter protein, allows the cells to expel the wide range of chemotherapeutic drugs. The latest reports show that COX-2 expression and P-gp expression possess strong correlation with each other. In this research study, we generated the Multi-Drug Resistant HT29 Human colon cancer cells by treating the cells with increasing concentrations of a chemotherapeutic drug namely Doxorubicin Hydrochloride (DOX) and further we estimated the intracellular drug concentration in treated live as well as dead cells with the help of Doxorubicin Accumulation Assay. Also, the cell morphology change was studied in HT29 cells after every 24 hours of the DOX treatment separately as well as curcumin co-treatment (DOX+Curcumin). The curcumin co-treatment was carried out to observe the effect of curcumin on multi-drug resistant HT29 colon cancer cells and further study can be extended to investigate the various inflammatory genes controlled by NFkB at mRNA and protein level as well as the levels of cytokines which may get down-regulated by treatment. This study will help to completely understand the mechanism of reducing the effect of Multidrug Resistance (a unique property of cancer) by curcumin in case of colon cancer.","PeriodicalId":22619,"journal":{"name":"The Journal of Cancer Research","volume":"1 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83711636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Defective DNA repair is a common imprint of cancer that promotes the accretion of DNA errors and genomic instability. The clustering of damage in DNA may stimulate breast carcinogenesis.

From March to December 2015, cervical samples from women attending cervical screening were tested for some HR to HPV. HPV DNA was amplified using PGMY09 /11 primers which generated 450 base pairs at the L1 region in which the samples harboring HPV DNA were genotyped using the multiplex PCR with HPV 16, 18, 31, 33, 35, 45 and 51 primers. The mean age of this population was 32 years and of about 339 women enrolled on visual inspection, 6.19% were positive. HPV DNA was obtained in 9.73 of the population in which 31 of 33 samples (93.93.%) of HPV DNA+ were genotyped using multiplex PCR testing for HPV 16,18, 31, 33, 35, 45 and 51, of those women with HPV DNA+; 28.57% had a single infection while 71.43% had a multiple infection. HPV genotypes prevalence followed: HPV 16 (30.00%), HPV 18 (25.00%), HPV35 (20.00%), HPV 45 (20.00%), HPV 51 (3.30%) and HPV 33 (1.60%), by using PCR as gold standard while VIA sensitivity and specificity was 16.12 and 95.45%, respectively. HPV prophylactic vaccine would prevent 33.33% of HR HPV infection with 2v, 33.33% with the 4v and 66.66% with the 9v vaccines, respectively. In Cote d'Ivoire screening for cervical cancer with HR HPV testing and triaging for treatment with visual inspection would represent a very efficient prevention of cervical cancer program. \u0000 \u0000 Key words: Human papillomaviruses (HPV), genotypes, acetic acid (IVA), Cote d’Ivoire.","PeriodicalId":22619,"journal":{"name":"The Journal of Cancer Research","volume":"251 1","pages":"7-15"},"PeriodicalIF":0.0,"publicationDate":"2017-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74505995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
