Randomized Controlled Trial
Clinical and cosmetic results of breast boost radiotherapy in early breast cancer: a randomized study between electron and photon.
Breast-conserving surgery followed by radiation therapy (RT) to the intact breast is now clearly established as the most acceptable strategy for women with early-stage invasive breast cancer. Recommended techniques for radiotherapy is whole breast irradiation (WBI) followed by boost to the tumor bed. ⋯ Both electrons and 3DCRT can be used for boost planning to the tumor bed in post-lumpectomy patients. Though there was slightly increased acute skin toxicity with 3DCRT photon which led to interruption of therapy, overall cosmesis at 2 years is similar in both modalities. 3DCRT boost is a better option than electrons dosimetrically, considering the fact that conformality; PTV coverage and OAR dosimetry were superior with photons. Thus in centers where electron beam therapy is not available, 3DCRT photon can be used effectively for tumor bed boost.

Comparative Study
A comparative study of set up variations and bowel volumes in supine versus prone positions of patients treated with external beam radiation for carcinoma rectum.
A prospective study was undertaken to evaluate the influence of patient positioning on the set up variations to determine the planning target volume (PTV) margins and to evaluate the clinical relevance volume assessment of the small bowel (SB) within the irradiated volume. ⋯ The prone position using BB device was more effective in reducing irradiated SB volume in rectal cancer patients. There were no significant variations in the daily set up for patients treated in both supine and prone positions.

Biopsy is an important diagnostic tool used in the diagnosis of lesions ranging from simple non-neoplastic, tumor-like lesions to malignancies, and is often the only way to diagnose oral lesions and diseases. The gingiva is the most common site for some kind of irritation or low-grade injury, resulting in localized overgrowths that are considered to be reactive and non-neoplastic lesions. This aim of this study is to analyze the frequency and distribution of gingival lesions in the Gujarati population. ⋯ It is difficult to compare studies carried out in various countries due to differences in people's attitudes toward oral health and the accessibility of various population groups to biopsy services. Nevertheless, this study has provided some information about the frequency and distribution of biopsied gingival lesions in the Gujarati population over a period of five years.
