Ductal carcinoma in situ (DCIS) is a premalignant condition that, if left untreated, may progress to invasive breast cancer. After lumpectomy, DCIS can recur, and about half of recurrences are invasive. In 4 randomized trials, radiation has been shown to decrease the local recurrence rate by about half, though it does not change survival. Based on the results of 3 randomized trials, tamoxifen probably decreases cancer recurrence by about 30%, particularly in young women. Low fat diets, weight loss, and physical activity decrease invasive breast cancer recurrence and may be recommended to certain women with DCIS. Prognostic factors include age, extent of DCIS, margin status, grade, and presence of necrosis, although how these affect adjuvant therapy is unclear. Research evaluating other drugs to reduce recurrence risk and on different ways of delivering radiation continues.

People living with HIV (PLWH) are diagnosed with cancer at an increased rate over the general population and generally have a higher mortality due to delayed diagnoses, advanced cancer stage, comorbidities, immunosuppression, and cancer treatment disparities. Lack of guidelines and provider education has led to substandard cancer care being offered to PLWH. To fill that gap, the NCCN Guidelines for Cancer in PLWH were developed; they provide treatment recommendations for PLWH who develop non–small cell lung cancer, anal cancer, Hodgkin lymphoma, and cervical cancer. In addition, the NCCN Guidelines outline advice regarding HIV management during cancer therapy; drug–drug interactions between antiretroviral treatments and cancer therapies; and workup, radiation therapy, surgical management, and supportive care in PLWH who have cancer.

As treatment of HIV has improved, people living with HIV (PLWH) have experienced a decreased risk of AIDS and AIDS-defining cancers (non-Hodgkin’s lymphoma, Kaposi sarcoma, and cervical cancer), but the risk of Kaposi sarcoma in PLWH is still elevated about 500-fold compared with the general population in the United States. The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for AIDS-Related Kaposi Sarcoma provide diagnosis, treatment, and surveillance recommendations for PLWH who develop limited cutaneous Kaposi sarcoma and for those with advanced cutaneous, oral, visceral, or nodal disease.
