Toxicity, Tolerability, and Compliance of Concurrent Capecitabine or 5-Fluorouracil in Radical Management of Anal Cancer With Single-dose Mitomycin-C and Intensity Modulated Radiation Therapy: Evaluation of a National Cohort.

Chemoradiation therapy (CRT) with mitomycin C (MMC) and 5-fluorouracil (5-FU) is established as the standard of care for the radical treatment of patients with anal squamous cell carcinoma (ASCC). The use of the oral fluoropyrimidine-derivative capecitabine is emerging as an alternative to 5-FU despite limited evidence of its tolerability and toxicity.

Intensity-modulated radiotherapy improves survival and reduces treatment time in squamous cell carcinoma of the anus: a National Cancer Data Base study.

Chemoradiation with 5-fluorouracil and mitomycin remains the standard of care for squamous cell carcinoma (SCC) of the anal canal. A prolonged treatment time is associated with inferior disease-specific outcomes. Radiation Therapy Oncology Group trial 0529 demonstrated decreased toxicity and fewer treatment breaks with intensity-modulated radiotherapy (IMRT), but this has not been assessed in a randomized trial. Using data from the National Cancer Data Base (NCDB), this study evaluated the impact of IMRT on...

Role of Immunotherapy in the Treatment of Squamous Cell Carcinoma of the Anal Canal.

Anal cancer is a rare malignancy for which cisplatin with 5-fluorouracil is the recommended treatment for patients with metastatic disease. Because most cases of anal cancer are linked to prior infection with oncogenic strands of the human papillomavirus, immunotherapeutic approaches have been of great interest in the development of new treatments for this virally driven tumor. This article reviews the early successes of anti-PD-1 therapies and adoptive T-cell therapies for metastatic anal cancer as a poten...

Inhibition of MAPKAPK2/MK2 facilitates DNA replication upon cancer cell treatment with gemcitabine but not cisplatin.

The signaling pathway driven by p38 and MAPKAPK2 alias MK2 is activated as part of stress responses, and these kinases represent attractive drug targets for cancer therapy. However, seemingly conflicting results were obtained when assessing the role of MK2 in chemotherapy. MK2 inhibitors were reported to either enhance or diminish the chemosensitivity of cancer cells. Here we show that this strongly depends on the particular chemotherapeutic drug. Two different MK2 inhibitors increased the proliferating fra...

Dose to Pelvic Bone Marrow Defined with FDG-PET Predicts for Hematologic Nadirs in Anal Cancer Patients Treated with Concurrent Chemo-radiation.

To investigate whether irradiated volume of pelvic active bone marrow (BM) may predict decreased blood cells nadirs in anal cancer patients undergoing concurrent chemo-radiation.

Anal Carcinoma, Version 2.2018, NCCN Clinical Practice Guidelines in Oncology.

The NCCN Guidelines for Anal Carcinoma provide recommendations for the management of patients with squamous cell carcinoma of the anal canal or perianal region. Primary treatment of anal cancer usually includes chemoradiation, although certain lesions can be treated with margin-negative local excision alone. Disease surveillance is recommended for all patients with anal carcinoma because additional curative-intent treatment is possible. A multidisciplinary approach including physicians from gastroenterology...

Feasibility of Neoadjuvant FOLFOX Therapy Without Radiotherapy for Baseline Resectable Rectal Cancer.

The combination of oxaliplatin, leucovorin and fluorouracil (FOLFOX) has been established as postoperative adjuvant chemotherapy for stage III colon cancer. However, the safety and efficacy of neoadjuvant FOLFOX in patients with rectal cancer are still controversial. This prospective pilot study aimed to evaluate the feasibility of neoadjuvant FOLFOX therapy without radiation for baseline resectable rectal cancer (RC).

Clinical Correlation of the Histoculture Drug Response Assay in Gastrointestinal Cancer.

The histoculture drug response assay (HDRA) with tumors histocultured on Gelfoamwas tested for clinical correlation for advanced gastric and colorectal cancer patients. In one study, 29 patients were treated with drugs shown to be ineffective in the HDRA, and all 29 cases showed clinical chemoresistance. In nine patients treated with drugs shown to be effective in the HDRA, six showed clinical chemoresponse and three showed arrest of disease progression. In a study of 32 patients with stage III and IV gastr...

Treatment of HPV-associated Anal Lesions in HIV-positive Patients - Comparison of Surgical Treatment and Topical Therapy with Imiquimod.

In HIV-patients, routine proctological assessment is warranted due to the high incidence of human papilloma virus (HPV) infection-related anogenital lesions, such as Condylomata acuminata (C. ac.), anal intraepithelial dysplasia (AIN) and anal cancer. For C. ac. and AIN, surgical resection and topical therapy with imiquimod have been discussed as treatment options.

Anal cytological lesions and HPV infection in individuals at increased risk for anal cancer.

Anal cytology may be useful for evaluating lesions associated with human papillomavirus (HPV) in individuals at increased risk for anal cancer.

The role of radiation therapy in the management of small cell lung cancer.

Small cell lung cancer (SCLC) is a very aggressive form of lung cancer. SCLC treatment requires multidisciplinary management and timely treatment. Radiation therapy is an important part of management of all stages of SCLC, in the curative as well as in the palliative setting. The role of radiation therapy in all stages of SCLC has changed in recent years; this article describes these changes and highlights the role of radiation therapy in the management of SCLC.

Palliative thoracic radiation therapy for non-small cell lung cancer: 2018 Update of an American Society for Radiation Oncology (ASTRO) Evidence-Based Guideline.

To revise the recommendation on the use of concurrent chemotherapy (CC) with palliative thoracic external beam radiation therapy (EBRT) made in the original 2011 American Society for Radiation Oncology guideline on palliative thoracic radiation for lung cancer.

A Population-Based Cohort Analysis of Chemoradiation Versus Radiation Alone for Definitive Treatment of Stage I Anal Cancer in Older Patients.

Although the benefit of chemoradiation over radiation therapy alone has been shown in randomized trials for stage II to III squamous cell of the anus, this benefit is not clear for patients with stage I cancer. Nevertheless, most societal recommendations endorse chemoradiation for patients with stage I squamous cell carcinoma of the anus despite the lack of proven benefit and potential increase in toxicity.

Anal cancer in high-income countries: Increasing burden of disease.

Previous studies have reported that anal cancer incidence has increased in individual countries; however, age-specific trends were not examined in detail. This study describes pooled and country-specific anal cancer incidence trends by sex, age (all ages,

CD44+/CD24+-Expressing Cervical Cancer Cells and Radioresistant Cervical Cancer Cells Exhibit Cancer Stem Cell Characteristics.

Radiation therapy is a mainstay in the treatment of cervical cancer. However, most advanced and metastatic cervical cancers are resistant to radiation therapy because of the presence of cancer stem cells (CSCs). To date, no specific markers were found for cervical CSCs.

LDR reverses DDP resistance in ovarian cancer cells by affecting ERCC-1, Bcl-2, Survivin and Caspase-3 expressions.

Ovarian cancer is the most frequent cause of death resulting from malignant gynecological tumors. After surgical intervention, cisplatin (DDP) is a major chemotherapy drug for ovarian cancer, but the ovarian cancer cells tend to develop DDP resistance in the clinical setting. Tumor cells are sensitive to low-dose radiation (LDR). However, how the LDR therapy improves the effects of chemotherapy drugs on ovarian cancer is not well understood. This study aimed to explore this issue.

Survival of patients with head and neck cancer treated with definitive radiotherapy and concurrent cisplatin or concurrent cetuximab: A Surveillance, Epidemiology, and End Results-Medicare analysis.

Cisplatin and cetuximab are both systemic therapies commonly used in combination with radiation (RT) for the definitive treatment of head and neck cancers, but their comparative efficacy is unclear.

The transcription-independent mitochondrial cell death pathway is defective in non-transformed cells containing the Pro47Ser variant of p53.

Approximately half of all human cancers contain mutations in the TP53 tumor suppressor. In addition to mutations, there are single nucleotide polymorphisms (SNPs) in TP53 that can dampen p53 function, and can increase cancer risk and decrease the efficacy of cancer therapy. Approximately 6% of Africans and 1% of African-Americans express a p53 allele with a serine instead of proline at position 47 (Pro47Ser, or S47). The S47 variant is associated with increased breast cancer risk in pre-menopausal African A...

Microneedle-Mediated Delivery of Lipid-Coated Cisplatin Nanoparticles for Efficient and Safe Cancer Therapy.

Cisplatin is the first-line chemotherapeutic agent, but its systemic toxicity and side effects severely limit its clinical use. We report a microneedle technique to mediate the transdermal delivery of lipid-coated cisplatin nanoparticles (LCC-NPs) for efficient and safe cancer therapy. Cisplatin was encapsulated by tumor-targeting pH-responsive lipid nanoparticles with a high loading rate of 80%, and the encapsulation substantially increased the solubility of cisplatin and enhanced its antitumor efficiency ...

Fucoidan Upregulates TLR4/CHOP-Mediated Caspase-3 and PARP Activation to Enhance Cisplatin-Induced Cytotoxicity in Human Lung Cancer Cells.

Cisplatin-based therapy is a traditional, clinical treatment for cancers, including lung cancer. In this study, we found that sequential therapy, i.e., cisplatin followed by fucoidan, reduced tumor volume in an LLC1-bearing C57BL/6 mouse model. Using a series of combined therapeutic experiments, we found that the inhibition rate of the sequential treatment (cisplatin→fucoidan) was 50 ∼ 75%. However, the inhibition rate of the sequential treatment, with fucoidan pretreatment, was increased to 75 ∼ 85%....

Mebendazole potentiates radiation therapy in triple-negative breast cancer.

The lack of a molecular target in triple negative breast cancer (TNBC) makes it one of the most challenging breast cancers to treat. Radiation therapy (RT) is an important treatment modality for managing breast cancer, however we previously showed that RT can also reprogram a fraction of the surviving BC cells into BC initiating cells (BCICs), that are thought to contribute to disease recurrence. In this study we characterize mebendazole as a drug with potential for preventing radiation-induced reprogrammin...

Outcome of surgery for recurrent anal cancer - results from a tertiary referral centre.

Chemoradiotherapy remains the first line treatment for anal cancer with surgery reserved for cancer recurrence or persistence. The low incidence of anal cancer means the numbers undergoing surgery is small with centralization for excision to regional cancer centres. We present our experience of abdominal perineal excision, with reconstruction of the perineal defect (APERR), within a tertiary centre.

Development and Calibration of a Mathematical Model of Anal Carcinogenesis for High-Risk HIV-Infected Men.

Men who have sex with men (MSM) who are living with human immunodeficiency virus (HIV) are at highest risk for anal cancer. Our objective was to use empirical data to develop a comprehensive disease simulation model that reflects the most current understanding of anal carcinogenesis, which is uniquely positioned to evaluate future anal cancer screening strategies as well as provide insight on the unobservable course of the disease.
