Randomized Controlled Trial Comparative Study Clinical TrialProspective comparison of breast pain in patients participating in a randomized trial of breast-conserving surgery and tamoxifen with or without radiotherapy.
To determine whether breast pain affects quality of life (QOL) after breast-conserving surgery and tamoxifen (TAM) with or without adjuvant breast radiotherapy (RT). ⋯ These results suggest that breast RT does not significantly contribute to breast pain or adversely impact the QOL up to 12 months after treatment in postmenopausal patients with node-negative breast cancer who take TAM.

PET-guided IMRT for cervical carcinoma with positive para-aortic lymph nodes-a dose-escalation treatment planning study.
To evaluate a treatment planning method for dose escalation to the para-aortic lymph nodes (PALNs) based on positron emission tomography (PET) with intensity-modulated radiotherapy (IMRT) for cervical cancer patients with PALN involvement. One goal of this process was not to modify the traditional treatment of the pelvic region. ⋯ This study indicates that PET-guided IMRT could be used in a clinical trial in an attempt to escalate doses delivered to patients with cervical cancer who have positive PALNs.

Analysis of in-field control and late toxicity for adults with early-stage Hodgkin's disease treated with chemotherapy followed by radiotherapy.
We analyzed in-field (IF) control in adults with early-stage Hodgkin's disease who received chemotherapy followed by radiotherapy (RT) in terms of the (1) chemotherapeutic regimen used and number of cycles delivered, (2) response to chemotherapy, and (3) initial tumor size. Cardiac toxicity and second malignancies, particularly the incidence of solid tumors in terms of the RT field size treated, were also examined. ⋯ In patients with nonbulky disease, induction chemotherapy followed by RT to a median dose of 40.0 Gy resulted in excellent IF control, regardless of the chemotherapeutic regimen used, the fact that only 1-2 cycles of chemotherapy were delivered, and the response to chemotherapy. There was a trend toward a higher incidence of solid tumors in patients who received consolidation RT to both sides rather than only one side of the diaphragm. Ongoing Phase III trials will help clarify whether lower RT doses and smaller RT fields after chemotherapy can maintain the IF control seen in our study, but with a lower incidence of late complications in patients with Stage I or II Hodgkin's disease.
