Lower-Limb Lymphedema after Sentinel Lymph Node Biopsy in Cervical Cancer Patients.

BACKGROUND: To prospectively assess LLL incidence among cervical cancer patients treated by uterine surgery complemented by SLN biopsy, without PLND. METHODS: A prospective study in 150 patients with stage IA1-IB2 cervical cancer treated by uterine surgery with bilateral SLN biopsy. Objective LLL assessments, based on limb volume increase (LVI) between pre- and postoperative measurements, and subjective patient-perceived swelling were conducted in six-month periods over 24-months post-surgery. RESULTS: The cumulative incidence of LLL at 24 months was 17.3% for mild LLL (LVI 10-19%), 9.2% for moderate LLL (LVI 20-39%), while only one patient (0.7%) developed severe LLL (LVI > 40%). The median interval to LLL onset was nine months. Transient edema resolving without intervention within six months was reported in an additional 22% of patients. Subjective LLL was reported by 10.7% of patients, though only a weak and partial correlation between subjective-report and objective-LVI was found. No risk factor directly related to LLL development was identified. CONCLUSIONS: The replacement of standard PLND by bilateral SLN biopsy in the surgical treatment of cervical cancer does not eliminate the risk of mild to moderate LLL, which develops irrespective of the number of SLN removed.

Voiding recovery after radical parametrectomy in cervical cancer patients: An international prospective multicentre trial - SENTIX.

OBJECTIVE: Voiding dysfunctions represent a leading morbidity after radical hysterectomy performed in patients with early-stage cervical cancer. The aim of this study was to perform ad hoc analysis of factors influencing voiding recovery in SENTIX (SENTinel lymph node biopsy in cervIX cancer) trial. METHODS: The SENTIX trial (47 sites, 18 countries) is a prospective study on sentinel lymph node biopsy without pelvic lymphadenectomy in patients with early-stage cervical cancer. Overall, the data of 300 patients were analysed. Voiding recovery was defined as the number of days from surgery to bladder catheter/epicystostomy removal or to post-voiding urine residuum ≤50 mL. RESULTS: The median voiding recovery time was three days (5th-95th percentile: 0-21): 235 (78.3%) patients recovered in <7 days and 293 (97.7%) in <30 days. Only seven (2.3%) patients recovered after >30 days. In the multivariate analysis, only previous pregnancy (p = 0.033) and type of parametrectomy (p < 0.001) significantly influenced voiding recovery >7 days post-surgery. Type-B parametrectomy was associated with a higher risk of delayed voiding recovery than type-C1 (OR = 4.69; p = 0.023 vs. OR = 3.62; p = 0.052, respectively), followed by type-C2 (OR = 5.84; p = 0.011). Both previous pregnancy and type C2 parametrectomy independently prolonged time to voiding recovery by two days. CONCLUSIONS: Time to voiding recovery is significantly related to previous pregnancy and type of parametrectomy but it is not influenced by surgical approach (open vs minimally invasive), age, or BMI. Type B parametrectomy, without direct visualisation of nerves, was associated with longer recovery than nerve-sparing type C1. Importantly, voiding dysfunctions after radical surgery are temporary, and the majority of the patients recover in less than 30 days, including patients after C2 parametrectomy.

Análisis de la casuística de metástasis ováricas de cáncer de mama del Instituto de Oncología Á. H. Roffo / Analysis of the casuistry of ovarian metastases in breast cancer at the Ángel H. Roffo Oncology Institute

Objetivo El objetivo del presente trabajo es analizar las características de las pacientes con antecedente de cáncer de mama que desarrollaron metástasis ováricas. Material y método Se identificaron casos entre enero de 2000 y diciembre de 2017. Se estudiaron las siguientes variables: edad al inicio y edad de la aparición de la metástasis ovárica; tipo histológico; perfil ihq del tumor mamario y anexial; estadio; uni o bilateralidad; tratamiento; latencia entre primario de mama y secundarismo en ovario; presentación; diagnóstico presuntivo preoperatorio; tipo de cirugía: tratamiento posterior; sle y sg. Resultados Se identificaron 17 casos. La incidencia de metástasis ováricas de cáncer de mama fue del 0,3%. El 82% se presentó en premenopáusicas. En cuanto al tipo: 50% fueron ductales, 43,7% lobulillares y 6,2% ductolobulillares. El perfil inmunohistoquímico fue: 62,5% Luminales B y 40% Luminales A. Todas las pacientes presentaban otros sitios de metástasis a distancia. El 62,5% fueron bilaterales y el 68,7% menores de 10 cm. La inmunohistoquimica demostró que el 53,3% modificó sus características. El tiempo de latencia entre ambos eventos, definida como punto de corte antes o después de los 5 años del primario, resultó en una diferencia marcada con sobrevida promedio de 88,5 meses para las primeras y de 154,4 meses para las segundas, pero no resultó estadísticamente significativa. Conclusiones La metástasis ovárica de cáncer mamario es un evento infrecuente. Suele aparecer en pacientes jóvenes premenopáusicas. El tipo histológico más frecuente es el lobulillar y el perfil molecular predominante es el Luminal B. La aparición de masas anexiales bilaterales sólidas o sólido-quísticas menores de 10 cm en pacientes con enfermedad diseminada debe hacer sospechar este diagnóstico

Objective Analyze the characteristics of patients with a history of breast cancer who developed ovarian metastases. Materials and method Identification of cases between January and December of 2017. Variables studied: age at onset and of the appearance of ovarian metastasis; histological type; ihc profile of breast and adnexal tumor; stage; unit or bilaterality; treatment; latency between primary breast and ovarian secondary; presentation; preoperative diagnosis; type of surgery; subsequent treatment; les and sg. Results 17 cases identified. The incidence of ovarian metastases from breast cancer was 0.3%, 82% premenopausal. 50% were ductal, 43.7% lobulillar and 6.2% ductolobulillar. The molecular profile was 62.5% Luminal A and 40% Luminal B. All the patients presented other sites of distant metastasis. 62.5% were bilateral and 68.7% were less than 10 cm. Immunohistochemistry showed that 53.3% modified its characteristics. The time elapsed between events, defined as a cut-off point before or after 5 years of the primary, resulted in a marked difference with average survival of 88.5 months for the first and 154.4 months for the second, but not statistically significant. Conclusions Ovarian metastasis of breast cancer is an infrequent event. It usually appears in young premenopausal patients. Lobular histological type and Luminal B molecular profile are predominant. The appearance of adjoining or more solid masses smaller than 10 cm in patients with disseminated disease should raise suspicion this diagnos

Sarcoma de mama. Experiencia en el Instituto Oncológico Ángel H. Roffo (ioar) / Breast Sarcoma. Experience at the Angel H. Roffo Institute (ioar)

Introducción Los sarcomas de mama son una entidad oncológica poco frecuente y heterogénea, por lo cual la literatura se limita a pequeñas revisiones retrospectivas e informes de casos. Por tal motivo, no hay consenso sobre su diagnóstico, tratamiento y seguimiento. Objetivo Sobre la base de un trabajo retrospectivo de la experiencia en el Instituto Ángel H. Roffo en el período comprendido entre 2000 y 2018, el estudio se propuso: a) analizar las propiedades de la enfermedad en cada paciente; b) evaluar el seguimiento, la sobrevida y las características de la población en estudio, acrecentando la interpretación de una entidad poco frecuente. Material y método Se trata de un trabajo retrospectivo, descriptivo, observacional que abarca los últimos 18 años de experiencia en esta patología en el Instituto Oncológico Ángel H. Roffo. Resultados Fueron diagnosticados y tratados 20 casos: 19 mujeres y 1 hombre. La incidencia fue de 0,36% sobre un total de 5.442 pacientes ingresados. La media de edad al diagnóstico fue de 50,5 años y la mediana de 49,3 años. Al separar los casos en intervalos de cada 2 décadas, se encontró que 6 pacientes tenían entre 20-30 años, 9 entre 40-59 años y 5 más de 60 años. Según el subtipo histológico, el orden de frecuencia fue el siguiente: 10 Sarcomas Fusocelulares; 2 Angiosarcomas; 1 Mixofibrosarcoma; 1 Cistosarcoma; 1 Liposarcoma Pleomorfo; 1 Dermatofibrosarcoma Protuberans; 1 Osteosarcoma. En tres casos no se obtuvieron datos por pérdida de historia clínica. La sobrevida libre de enfermedad y la sobrevida global se analizaron utilizando las curvas de Kaplan-Meier, siendo respectivamente de 152 y 260 meses. Conclusiones En conclusión, determinamos que el manejo multidisciplinario de la enfermedad en estadios iniciales ha demostrado una buena sobrevida global en la población evaluada

Introduction Breast sarcomas are a rare and heterogeneous oncological entity, so the literature is limited to small retrospective reviews and case reports. For this reason there is no consensus on its diagnosis, treatment and follow-up. Objective Based on a retrospective work of the experience at the Angel H. Roffo Institute in the period between 2000 and 2018, the study proposed: a) analyze the properties of the patient's disease; b) evaluate the monitoring, survival and characteristics of the study population, increasing the interpretation of a rare entity. Materials and method It is a retrospective, descriptive, observational work that covers the last 18 years of experience on this pathology at the Angel H. Roffo Institute. Results A total of 20 cases were diagnosed and treated: 19 women and 1 man. The incidence was 0,36% out of a total of 5,442 patients admitted. The mean age at diagnosis was 50.5 years and the median was 49.3 years. When we separate the cases every 2 decades, it was found that 6 patients are between 20-30 years old, 9 between 40-59 years old and 5 were more than 60 years old. According to the histological subtype, the frequency order was the follow: 10 Fusocelullar Sarcomas; 2 Angiosarcomas; 1 Mixofibrosarcoma; 1 Cystosarcoma; 1 Liposarcoma Pleomorfo; 1 Dermatofibrosarcoma Protuberans; 1 Osteosarcoma. In 3 cases no data were obtained due to loss of clinical history. Disease-free survival and overall survival were analyzed using the Kaplan-Meier curves, respectively 152 and 260 months. Conclusions In conclusion, we determined that the multidisciplinary management of the disease, in initial stages, has demonstrated a good overall survival in the evaluated population

Multicenter comprehensive methodological and technical analysis of 832 pressurized intraperitoneal aerosol chemotherapy (PIPAC) interventions performed in 349 patients for peritoneal carcinomatosis treatment: An international survey study.

BACKGROUND: Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a new drug delivery method offered in selected patients suffering from non-resectable peritoneal carcinomatosis (PC). As reported experience is still limited, we conducted a survey among active PIPAC centers aiming to report their technical approach and clinical findings. METHODS: An online survey was sent to active PIPAC centers worldwide. The questionnaire consisted of 34 closed questions and was conducted over a period of 3 months beginning in March 2017. RESULTS: Nine out of 15 contacted centers completed the questionnaire totaling 832 PIPAC procedures in 349 patients. Most common indications for PIPAC were PC from gastric, ovarian and colorectal origin. The mean time between each PIPAC procedure was 6-8 weeks. Seven of nine (77.8%) centers evaluate the PCI at every PIPAC procedure. At least four tissue samples for histopathology analysis were retrieved in 5 (55.6%). All centers (100%) use the same chemotherapy protocol: oxaliplatin at a dosage of 92mg/m2 for PC of colorectal origin and a combination of cisplatin and doxorubicin at a dosage of 7.5mg/m2 and 1.5mg/m2, respectively, for other types of PC. Eight centers (88.9%) perform routine radiological evaluation before first PIPAC and after third PIPAC. CONCLUSION: These data confirm that PIPAC procedures are homogeneously performed in established centers. Standardization of the procedure will facilitate future international multicenter prospective clinical trials.
