Colorectal cancer is the third most common malignant tumor among men, and the second most common malignant tumor among women worldwide. As one of the most common malignant tumor, colorectal cancer has a great threat to the health of people. Although the development of radiotherapy and chemotherapy could improve the prognosis of colorectal cancer, surgery, the complete resection of the tumor, remains the only chance for the cure of this disease. Over the past hundred years, surgical oncology went in the direction of protecting organ function and improving quality of life...

Oral mucositis (OM) is a frequent and severe adverse effect of therapy against head and neck cancer. Photobiomodulation with the low-power laser is known to be effective against OM, but the diversity of protocols and the possibility of stimulating residual tumor cells are still obstacles. The present study aimed to compare two doses of laser energy delivered to the oral mucosa of patients under oncologic treatment for head and neck cancer, looking for differences in the control of mucositis, as well as in the frequency of tumoral recurrences...

PURPOSE: Radiotherapy is a common adjuvant treatment of breast cancer. Acute radiation-induced dermatitis is a frequent side effect. We hypothesized whether it is possible to capture the increase of local temperature as a surrogate of the inflammatory state induced by radiotherapy. We designed a prospective, observational, single-centre study to acquire data on temperature rise in the treated breast during the course of radiotherapy, establish a possible association with the occurrence of dermatitis and investigate the predictive value of temperature increase in future occurrences of radiation-induced dermatitis...

BACKGROUND: An inflammatory myofibroblastic tumour (IMFT) is a rare mesenchymal neoplasm characterised by anaplastic lymphoma kinase (ALK) gene rearrangements. We assessed the activity and safety of crizotinib, a tyrosine kinase inhibitor, targeting ALK in patients with advanced IMFT either with or without ALK alterations. METHODS: We did a multicentre, biomarker-driven, single-drug, non-randomised, open-label, two-stage phase 2 trial (European Organisation for Research and Treatment of Cancer 90101 CREATE) at 13 study sites (five university hospitals and eight specialty clinics) in eight European countries (Belgium, France, Germany, Italy, Netherlands, Poland, Slovakia, and the UK)...

BACKGROUND: Patients' selection for transanal endoscopic microsurgery (TEM) depends on diagnostic modalities; however, there are still some limitations in the preoperative diagnosis of rectal lesions, and in some reports, up to third of the adenomas resected by TEM were found to be adenocarcinoma; therefore, salvage radical resection (RR) remains necessary for achieving oncological resection. Salvage RR may encounter some technical problems as the violation of the mesorectum and the scar formation...

Cytotoxic chemotherapies, molecularly targeted therapies, immunotherapies, radiotherapy, stem cell transplants, and endocrine therapies may lead to hair disorders (including alopecia, hirsutism, hypertrichosis, pigmentary and textural hair changes). The mechanisms underlying these changes are varied and remain incompletely understood, hampering the development of preventive or therapeutic guidelines. The psychosocial impact of chemotherapy -induced alopecia has been well-documented mainly in the oncology literature, however the effect of other alterations such as radiation-induced alopecia, hirsutism, changes in hair color or texture on quality of life have not been described...

Chemotherapy concurrent with radiotherapy has been widely used in clinical practice because the additional benefit on radiotherapy alone had shown. Head and neck cancer: CDDP concurrent with radiotherapy has been a standard treatment for 15years both in definitive setting and postoperative setting. Esophageal cancer: 5-FU/CDDP is the best partner for radiotherapy and appropriate radiation dose has been discussed. Anal cancer: Radical concurrent chemoradiotherapy with 5-FU and mitomycin C(MMC)remains the standard of care for squamous cell carcinoma of the anus...

Glioma is the most common primary cancer of the central nervous system, and around 50% of patients present with the most aggressive form of the disease, glioblastoma. Conventional therapies, including surgery, radiotherapy, and pharmacotherapy (typically chemotherapy with temozolomide), have not resulted in major improvements in the survival outcomes of patients with glioblastoma. Reasons for this lack of progress include invasive tumour growth in an essential organ, which limits the utility of local therapy, as well as the protection of tumour cells by the blood-brain barrier, their intrinsic resistance to the induction of cell death, and lack of dependence on single, targetable oncogenic pathways, all of which impose challenges for systemic therapy...

The reduction in the burden related to treatment is becoming more and more important in modern oncology. Radiation therapy is a mainstay option in the postoperative setting for early breast cancer patients after breast-conserving surgery. Nowadays, different options are available to de-escalate radiotherapy in this scenario such as the use of hypofractionated whole-breast radiation, the selective delivery of the boost dose to the lumpectomy cavity, the introduction of accelerated partial breast irradiation and the omission of treatment in appropriately selected patients with low-risk features...
