Purpose To investigate whether initial diagnostic laparoscopy can prevent futile primary cytoreductive surgery (PCS) by identifying patients with advanced-stage ovarian cancer in whom > 1 cm of residual disease will be left after PCS. Patients and Methods This multicenter, randomized controlled trial was undertaken within eight gynecologic cancer centers in the Netherlands. Patients with suspected advanced-stage ovarian cancer who qualified for PCS were eligible. Participating patients were randomly assigned to either laparoscopy or PCS. Laparoscopy was used to guide selection of primary treatment: either primary surgery or neoadjuvant chemotherapy followed by interval surgery. The primary outcome was futile laparotomy, defined as a PCS with residual disease of > 1 cm. Primary analyses were performed according to the intention-to-treat principle. Results Between May 2011 and February 2015, 201 participants were included, of whom 102 were assigned to diagnostic laparoscopy and 99 to primary surgery. In the laparoscopy group, 63 (62%) of 102 patients underwent PCS versus 93 (94%) of 99 patients in the primary surgery group. Futile laparotomy occurred in 10 (10%) of 102 patients in the laparoscopy group versus 39 (39%) of 99 patients in the primary surgery group (relative risk, 0.25; 95% CI, 0.13 to 0.47; P < .001). In the laparoscopy group, three (3%) of 102 patients underwent both primary and interval surgery compared with 28 (28%) of 99 patients in the primary surgery group ( P < .001). Conclusion Diagnostic laparoscopy reduced the number of futile laparotomies in patients with suspected advanced-stage ovarian cancer. In women with a plan for PCS, these data suggest that performance of diagnostic laparoscopy first is reasonable and that if cytoreduction to < 1 cm of residual disease seems feasible, to proceed with PCS.

Age-related decline of fertility in women is the result of the decline in both quantity and quality of the resting ovarian follicle pool. The aim of the present study was to determine whether the decline of follicle quality with age is reflected by ultrastructural changes in the resting follicle pool. Ovarian biopsy specimens were obtained by laparoscopy from seven healthy women aged 25-32 yr (young group) and from 11 healthy women aged 38-45 yr (advanced-age group). A total of 182 resting follicles from the young group were compared with 81 resting follicles from the advanced-age group for signs of age-related changes by transmission-electron microscopy. The ooplasmic fraction of vacuoles was increased (P = 0.02), and the fraction of mitochondria decreased (P = 0.005), in the advanced-age group. Also, the density of the mitochondrial matrix (P < 0.001) and the frequency of dilated smooth endoplasmic reticulum (SER; P = 0.001) and Golgi complex (P = 0.02) were increased with age. The frequencies of ruptured mitochondrial membranes (P = 0.001) and dilated SER (P = 0.003) were increased with age in the granulosa cells. Overall follicle-quality scores, which should reflect atretic changes, were not different for the young and advanced-age groups. In conclusion, in resting follicles, the morphological changes with age are different from the changes seen in quality decline by atresia. The morphological changes with age specifically involved the mitochondria, the SER, and the Golgi complex, and they may be the cause of atresia on initiation of follicular growth because of the substantial increase in metabolic requirements.

In humans, follicle quantity and quality decline with age by atresia. In the present study we aimed to describe the quality of the follicle pool through an ultrastructural investigation of resting follicles in young healthy women. From ovarian biopsies of 7 women aged 25-32 yr, 182 small follicles were morphometrically assessed for various signs of atresia. Morphometric variables were analyzed by principal components analysis (PCA) to demonstrate correlations between variables and to construct an objective follicle score. One third of small follicles consisted of primordial follicles. Nucleus:cell ratios remained constant for oocytes and granulosa cells from primordial to primary follicles, suggesting that follicles up to primary stages belong to the resting pool. The distribution of follicle quality scores as derived from PCA showed that most follicles were of good quality and with little signs of atresia. Atresia in resting follicles appears to be a necrotic process, starting in the ooplasma. Early atresia was characterized by increasing numbers of multivesicular bodies and lipid droplets, dilation of smooth endoplasmic reticulum and Golgi, and irregular mitochondria with changed matrix density. In progressive atresia mitochondrial membranes ruptured, oocyte nuclear membranes were indented or ruptured, and the ooplasma showed extensive vacuolarization. The early involvement of mitochondria in this process suggests that damage is induced by oxygen radicals. PCA follicle quality scores can be reliably approximated using a reduced number of seven morphometric variables, which were selected by stepwise forward analysis. The algorithm to calculate these follicle scores is presented.
