ABSTRACT
OBJECTIVE: The etiology of inferior oncologic outcomes associated with minimally invasive surgery for early-stage cervical cancer remains unknown. Manipulation of lymph nodes with previously unrecognized low-volume disease might explain this finding. We re-analyzed lymph nodes by pathologic ultrastaging in node-negative patients who recurred in the LACC (Laparoscopic Approach to Cervical Cancer) trial. METHODS: Included patients were drawn from the LACC trial database, had negative lymph nodes on routine pathologic evaluation, and recurred to the abdomen and/or pelvis. Patients without recurrence or without available lymph node tissue were excluded. Paraffin tissue blocks and slides from all lymph nodes removed by lymphadenectomy were re-analyzed per standard ultrastaging protocol aimed at the detection of micrometastases (>0.2 mm and ≤2 mm) and isolated tumor cells (clusters up to 0.2 mm or <200 cells). RESULTS: The study included 20 patients with median age of 42 (range 30-68) years. Most patients were randomized to minimally invasive surgery (90%), had squamous cell carcinoma (65%), FIGO 2009 stage 1B1 (95%), grade 2 (60%) disease, had no adjuvant treatment (75%), and had a single site of recurrence (55%), most commonly at the vaginal cuff (45%). Only one patient had pelvic sidewall recurrence in the absence of other disease sites. The median number of lymph nodes analyzed per patient was 18.5 (range 4-32) for a total of 412 lymph nodes. A total of 621 series and 1242 slides were reviewed centrally by the ultrastaging protocol. No metastatic disease of any size was found in any lymph node. CONCLUSIONS: There were no lymph node low-volume metastases among patients with initially negative lymph nodes who recurred in the LACC trial. Therefore, it is unlikely that manipulation of lymph nodes containing clinically undetected metastases is the underlying cause of the higher local recurrence risk in the minimally invasive arm of the LACC trial.

OBJECTIVE: The objective of this systematic review was to assess the oncologic and fertility outcomes of patients with cervix-confined cancer >4 cm who underwent neo-adjuvant chemotherapy followed by fertility-sparing surgery. METHODS: This study was registered in PROSPERO (registration number CRD42021254816). PubMed/MEDLINE, ClinicalTrials, EMBASE, Cochrane Central Register of Controlled Trials, SCOPUS, and OVID databases were searched from inception to July 2021. The included patients were those with cancer confined to the cervix and tumor diameter >4 cm (International Federation of Gynecology and Obstetrics (FIGO) 2018 stage IB3) with squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma who underwent intra-venous neo-adjuvant chemotherapy followed by successful fertility-sparing surgery. RESULTS: The initial search identified 2990 articles. A total of 40 patients from 11 studies had attempted fertility preservation surgery (conization, simple or radical trachelectomy) and in 26 patients (65%) it was successful. All patients received platinum-based chemotherapy. A complete pathological response occurred in 56% of patients and two patients (7.7%) had a recurrence. The 4.5-year disease-free survival was 92.3% and the 4.5-year overall survival rate was 100%. Of six patients who tried to conceive, four (67%) achieved at least one pregnancy and three of the five pregnancies (60%) were pre-term deliveries (all after radical trachelectomy). All patients with recurrence received cisplatin and ifosfamide instead of cisplatin and paclitaxel, underwent non-radical surgery, and had residual disease in the final specimen. CONCLUSIONS: Evidence for fertility-sparing surgery after neo-adjuvant chemotherapy in patients with cervical cancer and tumors >4 cm is limited, and this approach should be considered as an experimental intervention. As the use of non-radical surgery could be a risk factor, if neo-adjuvant chemotherapy is used, patients should undergo fertility-sparing radical surgery.

INTRODUCTION: Recent evidence has shown adverse oncological outcomes when minimally invasive surgery is used in early-stage cervical cancer. The objective of this study was to compare disease-free survival in patients that had undergone radical hysterectomy and pelvic lymphadenectomy, either by laparoscopy or laparotomy. METHODS: We performed a multicenter, retrospective cohort study of patients with cervical cancer stage IA1 with lymph-vascular invasion, IA2, and IB1 (FIGO 2009 classification), between January 1, 2006 to December 31, 2017, at seven cancer centers from six countries. We included squamous, adenocarcinoma, and adenosquamous histologies. We used an inverse probability of treatment weighting based on propensity score to construct a weighted cohort of women, including predictor variables selected a priori with the possibility of confounding the relationship between the surgical approach and survival. We estimated the HR for all-cause mortality after radical hysterectomy with weighted Cox proportional hazard models. RESULTS: A total of 1379 patients were included in the final analysis, with 681 (49.4%) operated by laparoscopy and 698 (50.6%) by laparotomy. There were no differences regarding the surgical approach in the rates of positive vaginal margins, deep stromal invasion, and lymphovascular space invasion. Median follow-up was 52.1 months (range, 0.8-201.2) in the laparoscopic group and 52.6 months (range, 0.4-166.6) in the laparotomy group. Women who underwent laparoscopic radical hysterectomy had a lower rate of disease-free survival compared with the laparotomy group (4-year rate, 88.7% vs 93.0%; HR for recurrence or death from cervical cancer 1.64; 95% CI 1.09-2.46; P=0.02). In sensitivity analyzes, after adjustment for adjuvant treatment, radical hysterectomy by laparoscopy compared with laparotomy was associated with increased hazards of recurrence or death from cervical cancer (HR 1.7; 95% CI 1.13 to 2.57; P=0.01) and death for any cause (HR 2.14; 95% CI 1.05-4.37; P=0.03). CONCLUSION: In this retrospective multicenter study, laparoscopy was associated with worse disease-free survival, compared to laparotomy.

BACKGROUND: Cervical cancer (CC) occupies fourth place in cancer incidence and mortality worldwide in women, with 560,505 new cases and 284,923 deaths per year. Approximately, nine of every ten (87%) take place in developing countries. When a macroscopic nodal involvement is discovered during a radical hysterectomy (RH), there is controversy in the literature between resect macroscopic lymph node compromise or abandonment of the surgery and sending the patient for standard chemo-radiotherapy treatment. The objective of this study is to compare the prognosis of patients with CC whom RH was abandoned and bilateral pelvic lymphadenectomy and para-aortic lymphadenectomy was performed with that of patients who were only biopsied or with removal of a suspicious lymph node, treated with concomitant radiotherapy/chemotherapy in the standard manner. METHODS: A descriptive and retrospective study was conducted in two institutions from Mexico and Colombia. Clinical records of patients with early-stage CC programmed for RH with an intraoperative finding of pelvic lymph, para-aortic nodes, or any extracervical involvement that contraindicates the continuation of surgery were obtained. Between January 2007 and December 2012, 42 clinical patients complied with study inclusion criteria and were selected for analysis. RESULTS: In patients with CC whom RH was abandoned due to lymph node affectation, there is no difference in overall survival or in disease-free period between systematic lymphadenectomy and tumor removal or lymph node biopsy, in pelvic lymph nodes as well as in para-aortic lymph nodes, when these patients receive adjuvant treatment with concomitant radiotherapy/chemotherapy. CONCLUSIONS: This is a hypothesis-generator study; thus, the recommendation is made to conduct randomized prospective studies to procure better knowledge on the impact of bilateral pelvic and para-aortic lymphadenectomy on this group of patients.

La Enfermedad Renal Crónica (ERC) se define como un proceso fisiopatológico de etiología múltiple que produce pérdida progresiva e inexorable del número funcional de nefronas, con la posibilidad de dar lugar a una condición denominada Insuficiencia Renal Crónica (IRC), la cual a su vez, conduce al paciente a depender permanentemente de una terapia de reemplazo renal. La ERC se define como: daño renal por ≥ 3 meses, definida por daño estructural o funcional con o sin disminución de la Rata de Filtración Glomerular (RFG), manifestada por anormalidades patológicas o marcadores de daño renal y por RFG < 60 m.l/min/1.73m2 por ≥ 3 meses, con o sin marcadores de daño renal; este es el parámetro que determina el estadío de la enfermedad renal (estadío 1- 5). Para el 2002 y basados en las estimaciones realizadas en la población norteamericana, aproximadamente ocho millones de personas presentaban una RFG menor a 60rnl/min/1.73m2 , lo cual corresponde a una enfermedad renal en estadío 3 o mayor. En números absolutos, la población con IRC en edades comprendidas entre los 45 y 64 años continúa creciendo y la incidencia total desde 1981 se ha cuadruplicado (de 82 a 334 por millón de habitantes). Sin importar la enfermedad renal subyacente (enfermedad primaria o secundaria), la progresión de la ERC deriva en un punto común, caracterizado por glomérulos escleróticos no funcionales, atrofia tubular y fibrosis intersticial, con la acumulación de "toxinas urémicas". Sin embargo, después de 150 años de ser descritas por vez primera, continúa siendo elusiva su adecuada caracterización. La ERC se acompaña de condiciones comórbidas como síndrome anémico, síndrome malnutrición-inflamación, acidemia/acidosis metabólica, dislipidemia, y enfermedad ósea que incrementan la morbi-mortalidad fundamentalmente de origen cardiovascular en este grupo de pacientes...
Chronic Kidney Disease is defined as a pathophysiologic process with multiple etiologies that produces a progressive and ineludible lost of the number of functional nephrones, with the possibility of giving place to a condition called Chronic Renal Failure, which itself drives the patient ro permanently depend on Renal Replacement Therapy. Chronic Renal disease is defined as: renal damage lasting 3 or more months, defined as structural or functional damage with or without decline in Glomerular filtration Rate (GFR), evidenced by pathological abnormalities or renal damage markers or GFR < 60ml/min/1.73 73m2 lasting 3 or more months, with or without renal damage markers. This is the parameter that establishes the stage of renal disease.In 2002 based on the estimates carried out in the North American population, approximately eight million people had a GFR < 60ml/min/1.73 111 2, which corresponds to a Renal Disease at least in Stage 3. In absolute numbers, the population with CRF between ages of 45 and 64 keeps growing and the total incidence since 1981 is four times bigger (82 to 334 per million habitants). Regardless of the underlying renal disease (primary or secondary), the progression of Chronic RenalDisease ends in a common point, characterized by sclerotic and non-functioning glomeruli, tubular atrophyand interstitial fibrosis, with the accumulation of «uremic toxins¼. Even though, after 150 years of being described for the first time, its adequate characterization is still elusive. Chronic Renal Disease has some associated conditions like anemic syndrome, malnutrition-inflammation syndrome, metabolic acidosis, dyslipidemia and bone disease that increases the morbimonality mainly cardiovascular morbilmortality, in this group of patients...
