We applaud the University of Texas Southwestern Department of Radiation Oncology for conducting “A phase II trial of stereotactic ablative radiotherapy as a boost for locally advanced cervical cancer,” a necessary prospective study on definitive dose delivery for patients unable to undergo brachytherapy.1 The involved trialists were undoubtedly deliberate and meticulous in its design and e xecution, akin to their groundbreaking work with lung stereotactic body radiation therapy (SBRT). Although these results unfortunately showed high rates of rectal toxicity, the data does not indicate a failure of SBRT, but rather an opportunity for further investigation.

Abstract Brachytherapy is an invasive therapy with placement of radiation source into or near the tumor. The difference between planning target volume and clinical target volume is minimal, and the dose out of the tumor reduces rapidly due to the inverse-square law. High-dose-rate brachytherapy enables three-dimensional image guidance, and currently, tumor dose as well as doses of the surrounding normal structures can be evaluated accurately. High-dose-rate brachytherapy is the utmost precision radiation therapy even surpassing carbon ion therapy. Biological disadvantages of high-dose rate have been overcome by th...

Conclusions: Our findings suggest that IMRT may represent a viable alternative in delivering the boost in patients diagnosed with gynaecological cancer not amenable to ICBRT. PMID: 32010217 [PubMed]

Conclusions: Our study confirms that the combination of IMRT and PDR-BT can be considered an effective treatment for cervical cancer, ensuring high local control, despite the high percentage of locally advanced disease. PMID: 31969909 [PubMed]

Abstract OBJECTIVE: To measure anti-glycan antibodies (AGA) in cervical cancer (CC) patient sera and assess their effect on therapeutic outcome. PATIENTS AND METHODS: Serum AGA was measured in 276 stage II and 292 stage III Peruvian CC patients using a high content and throughput Luminex multiplex glycan array (LMGA) containing 177 glycans. Association with disease-specific survival (DSS) and progression free survival (PFS) were analyzed using Cox regression. RESULTS: AGAs were detected against 50 (28.3%) of the 177 glycans assayed. Of the 568 patients, 84.5% received external beam radiation therapy (EBR...

Conclusion: The study did not demonstrate a significant benefit in administering resistant starch over and above normal diet to patients receiving pelvic radiotherapy. The reasons may be attributed to concurrent use of chemotherapy and decrease in intestinal probiotics. The use of digestible starch in the control arm may have contributed to lower incidence of the toxicity endpoints as well.

Our purpose was to assess the feasibility, safety, and efficacy of stereotactic ablative radiation therapy (SAbR) as an alternative for intracavitary/interstitial brachytherapy boost for locally advanced cervical cancer (LACC) after initial chemoradiation.

There is heterogeneity in brachytherapy treatment practice for cervical cancer across India. In an attempt to standardize various processes involved in cervical cancer brachytherapy, the expert members of the Indian Brachytherapy Society (IBS) developed a document related to radiation therapy treatment of cervical cancer with special emphasis on brach...

Conclusions: We found that the use of the hybrid applicator allowed for adequate target coverage in a patient with unusual anatomy. The patient tolerated treatment well and demonstrated favorable response on follow-up exam and imaging. The long-term curative result needs to be further evaluated. PMID: 31435436 [PubMed]

Conclusion: VMAT combined with IC/IS BT can result in satisfactory curative outcomes and low incidences of late radiation enterocolitis and cystitis in CC treatment.
