RESUMEN

The COVID-19 pandemic has forever affected healthcare and posed an incredible challenge to our society to care for our sick. Patients with cancer were found early on to have higher rates of complications with COVID-19. Radiation therapy is an integral part of treatment for many types of gynecologic cancer and adaptation on its utilization during the pandemic varied across the globe. In this review, we detail certain guidelines for the use of radiation in gynecologic cancers during the pandemic as well as real world accounts of how different countries adapted to these guidelines or created their own based on individualized resources, staffing, government restrictions, and societal norms. Critically, this review demonstrates the breadth of fractionation schemes and technologies used when resources were limited but highlights the importance of long term follow-up for many of our patients during this time.

RESUMEN

BACKGROUND: Cervical cancer is the leading cause of cancer death in Sub-Saharan Africa. The risk of developing cancer is increased for women living with human immunodeficiency virus (HIV) infection. It is unknown which factors predict the initiation of curative chemoradiotherapy (CRT) in resource-limited settings and whether HIV is associated with initiating curative CRT in settings with a high HIV burden. METHODS: All women living with and without HIV infection who were initiating curative and noncurative CRT for locally advanced cervical cancer in Botswana were prospectively enrolled in an observational study. The factors associated with receiving CRT were evaluated in all patients and the subgroup of women living with HIV. RESULTS: Of 519 enrolled women, 284 (55%) initiated CRT with curative intent. The curative cohort included 200 women (70.4%) who were living with HIV and had a median CD4 count of 484.0 cells/µL (interquartile range, 342.0-611.0 cells/µL). In the noncurative cohort, 157 of 235 women (66.8%) were living with HIV and had a median CD4 count of 476.5 cells/µL (interquartile range, 308.0-649.5 cells/µL). HIV status was not associated with initiating curative CRT (odds ratio [OR], 0.95; 95% confidence interval [CI], 0.58-1.56). The factors associated with receiving curative CRT treatment on multivariable analysis in all patients included baseline hemoglobin levels ≥10 g/dL (OR, 1.80; 95% CI, 1.18-2.74) and stage I or II versus stage III or IV disease (OR, 3.16; 95% CI, 2.10-4.75). Women aged >61 years were less likely to receive curative treatment (OR, 0.43; 95% CI, 0.24-0.75). Among women who were living with HIV, higher CD4 cell counts were associated with higher rates of CRT initiation. CONCLUSIONS: The initiation of CRT with curative intent does not depend on HIV status. Significant predictors of CRT initiation include baseline hemoglobin level, disease stage, and age.

RESUMEN

The majority of deaths from cervical cancer occur in low- and middle- income countries (LMICs). The standard of care for early-stage cervical cancer (FIGO 2018 IA2-IB1) is radical hysterectomy, a procedure performed by trained gynecologic oncologists. However, the lack of gynecologic oncologists in LMICs has required exploration into other methods of treatment for early-stage cervical cancer. A potential course of treatment for early-stage cervical cancer is neoadjuvant chemotherapy followed by simple hysterectomy and pelvic lymph node sampling, which can be performed by a general gynecologist. We gathered data for 8 women who underwent this method of treatment and found that cause-specific survival was 100% over a 3.5-year median follow-up. These findings support the exploration for this method of treatment for early-stage cervical cancer in LMICs, which would improve access to treatment for these women and hopefully reduce the high burden of cervical cancer related deaths in LMICs.

RESUMEN

BACKGROUND: Human papillomavirus type 16 (HPV16) is a common infection in the anogenital tract. HPV16 DNA detected in oral specimens has recently been identified as a risk factor for some oropharyngeal cancers. The reported prevalence of oral HPV infection from individual studies is highly variable. METHODS: We systematically reviewed and abstracted data from published studies (n = 18) that detected oral HPV DNA in 4581 cancer-free subjects to determine the pooled prevalence (and 95% confidence intervals [CI]) of HPV16, carcinogenic HPV, and any HPV. RESULTS: 1.3% (95% CI: 1.0-1.7%) of 3977 healthy subjects had oral HPV16, 3.5% (95% CI: 3.0-4.1) of 4441 subjects had carcinogenic HPV, and 4.5% (95% CI: 3.9-5.1) of 4070 subjects were positive for any HPV. Oral HPV16 accounted for 28% of all HPV detected in the oral region. Men (47 of 1017) and women (117 of 3690) had nearly exactly the same prevalence of any oral HPV detected (4.6% vs. 4.4%, respectively). CONCLUSIONS: HPV-16, a common anogenital infection, was rarely detected in oral specimens. However, a small but noteworthy proportion of healthy individuals have oral HPV infections with types known to cause cancer in the oral region.

RESUMEN

The use of brachytherapy for the treatment of gynecologic malignancies, particularly cervical cancer, has a long and rich history that is nearly as long as the history of radiation oncology itself. From the first gynecologic brachytherapy treatments in the early 20th century to the modern era, significant transformation has occurred driven largely by advancements in technology. The development of high-dose rate sources, remote afterloaders, novel applicators, and 3-dimensional image guidance has led to improved local control, and thus improved survival, solidifying the role of brachytherapy as an integral component in the treatment of locally advanced cervical cancer. Current research efforts examining novel magnetic resonance imaging sequences, active magnetic resonance tracking, and the application of hydrogel aim to further improve local control and reduce treatment toxicity.

RESUMEN

BACKGROUND: To characterize the clinico-pathological features including estrogen receptor (ER), progesterone receptor (PR) and Her-2/neu (HER2) expression in breast cancers in Botswana, and to compare them by HIV status. METHODS: This was a retrospective study using data from the National Health Laboratory and Diagnofirm Medical Laboratory in Gaborone from January 1, 2011 to December 31, 2015. Clinico-pathological details of patients were abstracted from electronic medical records. RESULTS: A total of 384 unique breast cancer reports met our inclusion criteria. Of the patients with known HIV status, 42.7% (50/117) were HIV-infected. Median age at the time of breast cancer diagnosis was 54 years (IQR 44-66 years). HIV-infected individuals were more likely to be diagnosed before age 50 years compared to HIV-uninfected individuals (68.2% vs 23.8%, p < 0.001). The majority of patients (68.6%, 35/51) presented with stage III at diagnosis. Stage IV disease was not presented because of the lack of data in pathology records surveyed, and additionally these patients may not present to clinic if the disease is advanced. Overall, 68.9% (151/219) of tumors were ER+ or PR+ and 16.0% (35/219) were HER2+. ER+ or PR+ or both, and HER2- was the most prevalent profile (62.6%, 132/211), followed by triple negative (ER-/PR-/HER2-, 21.3%, 45/211), ER+ or PR+ or both, and HER2+, (9.0%, 19/211) and ER-/PR-/HER2+ (7.1%, 15/211). There was no significant difference in receptor status noted between HIV-infected and HIV-uninfected individuals. CONCLUSIONS: Majority of breast cancer patients in Botswana present with advanced disease (stage III) at diagnosis and hormone receptor positive disease. HIV-infected breast cancer patients tended to present at a younger age compared to HIV-uninfected patients. HIV status does not appear to be associated with the distribution of receptor status in breast cancers in Botswana.

RESUMEN

Purpose Delays in diagnosis and treatment of cancers can lead to poor survival. These delays represent a multifaceted problem attributable to patient, provider, and systemic factors. We aim to quantify intervals from symptom onset to treatment start among patients with cancer in Botswana and to understand potential risk factors for delay. Patients and Methods From December 2015 to January 2017, we surveyed patients seen in an oncology clinic in Botswana. We calculated proportions of patients who experienced delays in appraisal (between detecting symptoms and perceiving a reason to discuss them with provider, defined as > 1 month), help seeking (between discussing symptoms and first consultation with provider, defined as > 1 month), diagnosis (between first consultation and receiving a diagnosis, defined as > 3 months), and treatment (between diagnosis and starting treatment, defined as > 3 months). Results Among 214 patients with cancer who completed the survey, median age at diagnosis was 46 years, and the most common cancer was cancer of the cervix (42.2%). Eighty-one percent of patients were women, 60.7% were HIV infected, and 56.6% presented with advanced cancer (stage III or IV). Twenty-six percent of patients experienced delays in appraisal, 35.5% experienced delays help seeking, 63.1% experienced delays in diagnosis, and 50.4% experienced delays in treatment. Patient income, education, and age were not associated with delays. In univariable analysis, patients living with larger families were less likely to experience a help-seeking delay (odds ratio [OR], 0.31; P = .03), women and patients with perceived very serious symptoms were less likely to experience an appraisal delay (OR, 0.45; P = .032 and OR, 0.14; P = .02, respectively). Conclusion Nearly all patients surveyed experienced a delay in obtaining cancer care. In a setting where care is provided without charge, cancer type and male sex were more important predictors of delays than socioeconomic factors.

RESUMEN

BACKGROUND: It is not known whether immune dysfunction is associated with increased risk of death after cancer diagnosis in persons with HIV (PWH). AIDS-defining illness (ADI) can signal significant immunosuppression. Our objective was to determine differences in cancer stage and mortality rates in PWH with and without history of ADI. METHODS: PWH with anal, oropharynx, cervical, lung cancers, or Hodgkin lymphoma diagnoses from January 2000 to December 2009 in the North American AIDS Cohort Collaboration on Research and Design were included. RESULTS: Among 81,865 PWH, 814 had diagnoses included in the study; 341 (39%) had a history of ADI at time of cancer diagnosis. For each cancer type, stage at diagnosis did not differ by ADI (P > 0.05). Mortality and survival estimates for cervical cancer were limited by n = 5 diagnoses. Adjusted mortality rate ratios showed a 30%-70% increase in mortality among those with ADI for all cancer diagnoses, although only lung cancer was statistically significant. Survival after lung cancer diagnosis was poorer in PWH with ADI vs. without (P = 0.0001); the probability of survival was also poorer in those with ADI at, or before other cancers although not statistically significant. CONCLUSIONS: PWH with a history of ADI at lung cancer diagnosis had higher mortality and poorer survival after diagnosis compared to those without. Although not statistically significant, the findings of increased mortality and decreased survival among those with ADI (vs. without) were consistent for all other cancers, suggesting the need for further investigations into the role of HIV-related immune suppression and cancer outcomes.
