Purpose: SIRFLOX was a randomized, multicenter trial designed to assess the efficacy and safety of adding selective internal radiation therapy (SIRT) using yttrium-90 resin microspheres to standard fluorouracil, leucovorin, and oxaliplatin (FOLFOX)-based chemotherapy in patients with previously untreated metastatic colorectal cancer.

Patients And Methods: Chemotherapy-naïve patients with liver metastases plus or minus limited extrahepatic metastases were randomly assigned to receive either modified FOLFOX (mFOLFOX6; control) or mFOLFOX6 plus SIRT (SIRT) plus or minus bevacizumab. The primary end point was progression-free survival (PFS) at any site as assessed by independent centralized radiology review blinded to study arm.

Numerous studies have examined the association between body weight, nutritional factors, physical activity and the risk for primary breast cancer. Relatively few studies, however, have examined the associations between these issues and the recurrence of the disease and cure of the primary tumor. Today, three areas of focus are actively being researched for breast cancer survivors: body weight, diet composition and physical activity with specific emphasis on the risk for recurrence, survival and quality of life.

Article Synopsis
  • LEFCT-EC is a novel cancer treatment combining low electric field stimulation and chemotherapy that has shown promising results in destroying mouse tumors and enhancing immune response.
  • Mice with colon carcinomas treated with LEFCT-EC had a cure rate of 93%, significantly outperforming other treatment methods like surgery and standard chemotherapy.
  • The findings indicate that LEFCT-EC not only directly eliminates tumors but also strengthens the body's immune response, particularly through CD4 and CD8 T cells, allowing for better protection against tumor recurrence.

Low electric field cancer treatment-enhanced chemotherapy (LEFCT-EC) is a new anticancer treatment which utilizes a combination of chemotherapeutic agents and a low electric field. We investigated the antitumour effectiveness of this technique in a model of murine colon carcinoma (CT-26). The low electric field was applied to approximately 65 mm3 intracutaneous tumours after intratumoral injection of 5FU, bleomycin or BCNU.

Diffusion-weighted magnetic resonance imaging (DWMRI) is sensitive to tissues' biophysical characteristics, including apparent diffusion coefficients (ADCs) and volume fractions of water in different populations. In this work, we evaluate the clinical efficacy of DWMRI and high diffusion-weighted magnetic resonance imaging (HDWMRI), acquired up to b = 4000 sec/mm(2) to amplify sensitivity to water diffusion properties, in pretreatment prediction of brain tumors' response to radiotherapy. Twelve patients with 20 brain lesions were studied.

  • The study investigates the genetic factors contributing to prostate cancer risk, focusing on various candidate genes in 224 Jewish Israeli patients.
  • Findings reveal that the EPHX gene His113 allele is significantly linked to late-onset prostate cancer and higher tumor grades.
  • Results suggest that while the EPHX allele may indicate more advanced disease, further research with a larger, diverse population is necessary to validate these findings.

Purpose: To study the feasibility of using diffusion-weighted magnetic resonance imaging (DWMRI), which is sensitive to the diffusion of water molecules in tissues, for detection of early tumor response to radiation therapy; and to evaluate the additional information obtained from high DWMRI, which is more sensitive to low-mobility water molecules (such as intracellular or bound water), in increasing the sensitivity to response.

Patients And Methods: Standard MRI and DWMRI were acquired before and at regular intervals after initiating radiation therapy for 10 malignant brain lesions in eight patients.

Results: One week posttherapy, three of six responding lesions showed an increase in the conventional DWMRI parameters.

Testicular cancer is the most common malignancy in young men. To evaluate knowledge and awareness of that cancer, and of the practice of testicular self-examination (TSE), we developed a questionnaire which was distributed to 717 male soldiers and 200 of their military physicians. 21% of the soldiers had received some explanation of the importance of TSE, but only 16% were actually instructed how to perform TSE, and only 2% practiced it regularly.

Background: Several studies have recently suggested that the immune response to malignant growths is regulated by distinct patterns of type 2 cytokine production. These cytokines, regulating the cytotoxic T-lymphocyte response in patients with advanced cancers, may be associated with disease progression. Evidence suggests that the T Helper 1 (TH1) and T Helper 2 (TH2) types of reaction are reciprocally regulated in vivo.

The immunomodulator AS101 has been demonstrated to exhibit radioprotective and chemoprotective effects in mice. Following phase-I studies, preliminary results from phase-II clinical trials on non-small-cell-lung-cancer patients showed a reduction in the severity of alopecia in patients treated with AS101 in combination with chemotherapy. To further substantiate these findings, the present study was extended to include 58 patients treated either with the optimal dose of 3 mg/m2 AS101 combined with carboplatin and VP-16, or with chemotherapy alone.
