Seventy years ago, Robin Mole introduced the concept of the abscopal effect to describe a rare phenomenon. This occurs when local radiation triggers an immune-mediated reduction in tumors outside the treated area but within the same organism. Observing this effect has been linked to improved overall and progression-free survival in patients who experience it.

Background: Adherence to clinical practice guidelines improves outcomes for patients with breast cancer. However, their implementation may not be feasible in low- and middle-income countries. This study aimed to evaluate physicians' adherence, attitudes, and barriers towards the Colima Consensus, which is the Mexican national breast cancer clinical practice guideline.

The Case A previously healthy woman, aged 32 years, presented to the oncology clinic with a 6-month history of left-breast tumor, mastalgia, and swollen axillary nodes. Physical examination was relevant for a 6-cm palpable mass in the upper outer quadrant of the left breast and an ipsilateral 2-cm, nonfixed axillary lymph node. Mammography showed a 1-cm mass in the upper outer quadrant, a 5.

Epithelial ovarian cancer (OC) is known to be a neoplasm responsive to radiotherapy (RT). Nevertheless, the role of RT in the management of this disease represent a topic of controversy, and the indications for its use are not fully established. Initial studies suggested that the addition of RT in the form of intraperitoneal (IP) radioisotopes was useful.

Aim: Our goal was to compare conformal 3D (C3D) radiotherapy (RT), modulated intensity RT (IMRT), and volumetric modulated arc therapy (VMAT) planning techniques in treating pituitary adenomas.

Background: RT is important for managing pituitary adenomas. Treatment planning advances allow for higher radiation dosing with less risk of affecting organs at risk (OAR).

Background And Objectives: The low availability and poor access to external beam radiotherapy (EBRT) in developing countries makes it hard for women with breast cancer to receive breast conservation. We studied the effect of providing intraoperative radiotherapy (IORT) on the travel time, distance, and costs of in the Mexico City Metropolitan Area (MCMA).

Methods: Sixty-nine patients treated between January 2013 and September 2014 were analyzed.

Intensity modulated radiation therapy (IMRT) allows physicians to deliver higher conformal doses to the tumour, while avoiding adjacent structures. As a result the probability of tumour control is higher and toxicity may be reduced. However, implementation of IMRT is highly complex and requires a rigorous quality assurance (QA) program both before and during treatment.

The bacillus Calmette-Guérin (BCG) is regarded as the most successful immunotherapy against superficial bladder carcinoma recurrences to date. BCG intravesical therapy for superficial bladder cancer has shown its efficacy and advantage over classical therapeutic strategies. This efficacy is based on complex and long lasting immune activation.
