Oncologic results of fertility sparing surgery of cervical cancer: An updated systematic review.

BACKGROUND: Several techniques can be proposed as fertility sparing surgery in young patients treated for cervical cancer but uncertaincies remain concerning their outcomes. Analysis of oncological issues is then the first aim of this review in order to evaluate the best strategy. RESULTS: Data were identified from searches of MEDLINE, Current Contents, PubMed and from references in relevant articles from January 1987 to 15th of September 2021. We carry out an updated systematic review involving 5862 patients initially selected for fertility-sparing surgery in 275 series. FINDINGS: In patients having a stage IB1 disease, recurrence rate/RR in patients undergoing simple conisation/trachelectomy, radical trachelectomy/RT by laparoscopico-vaginal approach, laparotomic or laparoscopic approaches are respectively: 4.1%, 4.7%, 2.4% and 5.2%. In patients having a stage IB2 disease, RR after neoadjuvant chemotherapy or RT by laparotomy are respectively 13.2% and 4.8% (p = .0035). After neoadjuvant treatment a simple cone/trachelectomy was carried out in 91 (30%) patients and a radical one in 210 (70%) cases. But the lowest pregnancy rate is observed in patients undergoing RT by laparotomy (36%). CONCLUSIONS: The choice between these treatments should be based above all, on objective oncological data that strike a balance for each procedure between the best chances for cure and the fertility results. In patients having a stage IB1 disease, oncological results are quite similar according to the procedure used. In patients having a stage IB2 disease, RT by open approach has the lowest RR. Anyway the lowest pregnancy rate is observed in patients undergoing RT by laparotomy.

Potential histological discordance revealed by second review in the national rare gynecological cancer network (TMRG).

INTRODUCTION: Since 2010, the network of rare malignant tumors of the ovary (TMRG) was developed to optimize the management of patients, also allowing a histological second opinion of rare ovarian tumors. The aim of this work was to study the contribution of second opinion to improve histological diagnostic accuracy on ovarian rare malignant tumors included in the TMRG database. MATERIAL AND METHODS: Histological data of patients diagnosed with a rare ovarian tumor included in TMRG network over a one-year period (2018) were collected. Initial diagnoses were compared with second opinion from national gynecological pathologist experts. The modalities of histological second opinion requests were studied, as well as the histological characteristics of the tumors. The discordances were classified as minor (if the modification of histological diagnosis did not change patient management) and major (if the patient management can be modified). RESULTS: Of 1185 included patients, 937 matched the inclusion criteria. Full concordance between primary diagnosis and expert second opinion was reached in 611 cases (65,3%), minor discordance was seen in 114 (12,2%) and major discordance in 209 (22,3%) of cases. In systematic review requested by the network, 26% (n = 137) of cases were reported with a change in histological diagnosis, while the change concerned 44% (n = 186) of cases for a second opinion spontaneously requested by the initial pathologist. The discrepancies concerned all categories of ovarian tumors, with a majority of mucinous tumors (43% of major discordances), followed by stromal and sex-cord tumors (13.8% of major discordances) and clear cell tumors (12,4% of major discordances). CONCLUSION: This analysis confirms the diagnostic difficulty of ovarian tumors, due to their rarity and morphological heterogeneity. French pathologists are aware of these difficulties and spontaneously refer ovarian tumors with unusual histology for a second opinion and collaborate with rare tumor networks for systematic review.

Comprehensive analysis of patient outcome after local recurrence of locally advanced cervical cancer treated with concomitant chemoradiation and image-guided adaptive brachytherapy.

INTRODUCTION: Since dose escalation allowed by image-guided adaptive brachytherapy (IGABT) in locally advanced cervical cancer (LACC), local relapses have become a rare event. Only scarce data are available on the outcome of patients experiencing a local relapse after IGABT. METHODS: Between 2004 and 2016, all consecutive patients treated at Gustave Roussy Institute for LACC and receiving concomitant chemoradiation and IGABT were analysed. Clinical and treatment-related prognostic factors for survival after local relapse were searched, in order to potentially identify patients requiring salvage treatment. RESULTS: Two hundred and fifty-nine patients were treated during this period. With a median follow-up of 4.1 years, 10.8% (n = 28) had a local relapse. Among these patients, 53.6% had synchronous lymph nodes or distant metastatic relapse and only 13 patients (5% of all patients) had isolated local relapse. After local relapse, median survival was 47 months and three patients were alive at last follow-up. Only three patients with local relapse could receive salvage surgery (10.7%). Metastases occurrence and pelvic wall involvement were the main contraindications (67.9%) for salvage surgery. Among the three patients treated with surgery, two are still alive at last follow-up without significant complication. Improved survival was observed among the two patients who could have surgery (p = .02). Local progression led to serious symptoms in 75% of patients. Only the time interval between brachytherapy and relapse (<1 year) was prognostic for 2-year overall survival (p = .005). CONCLUSION: Salvage surgery is feasible in a very low number of highly selected patients with local relapse following IGABT. Local failure is a major cause of severe local symptoms, confirming that every effort should be done to achieve long-term local control through dose escalation.

Impact of cancer chemotherapy before ovarian cortex cryopreservation on ovarian tissue transplantation.

STUDY QUESTION: How efficacious is transplantation of ovarian cortex previously exposed to chemotherapy? SUMMARY ANSWER: Prior exposure to chemotherapy did not disrupt the function of cryopreserved ovarian tissue after transplantation. WHAT IS KNOWN ALREADY: Ovarian tissue cryopreservation (OTC) followed by ovarian tissue transplantation (OTT) is an efficacious technique for restoration of female fertility. At least 130 children have been born following this procedure. To date, little is known about the efficacy of OTT in patients exposed to cancer chemotherapy prior to OTC. STUDY DESIGN, SIZE, DURATION: This study evaluates the recovery of ovarian function and fertility in 31 consecutive patients who had received OTT, between 2005 and 2015. PARTICIPANTS/MATERIALS, SETTING, METHODS: Thirty one patients, wanting children, were transplanted with autologous ovarian cortex, among which 22 patients (71%) had been exposed to chemotherapy before OTC. Recovery of ovarian function was considered total once menstruation occurred. Ovarian function recovery (OFR), ovarian graft survival, and incidence of pregnancy were related to previous chemotherapy exposure, type of chemotherapy and graft characteristics (number of grafted fragments and follicular density). MAIN RESULTS AND ROLE OF CHANCE: The amount of ovarian tissue collected was the only parameter to show any significant change between patients with versus without previous chemotherapy. At 1 year after OTT, the cumulative incidence of OFR was 83% (93% in patients exposed to chemotherapy and 67% in others (P = 0.14)). A low follicular density (<0.3 foll/mm2) in the transplant and a low number of grafted fragments (<16) were significantly associated with a delayed OFR. Graft survival at 2 years after OTT was 77%. It was significantly lower in patients exposed to bifunctional alkylating agents before ovarian cryopreservation and in patients with a low follicular density. The proportion of women who succeeded in having at least one live birth was 23% in the total population, 0% (0/9) in the group 'no previous chemotherapy', and 32% (7/22) in the group 'previous chemotherapy'. The cumulative incidence of pregnancy (Kaplan-Meier) at 3 years after OTT was 36% overall and 49% in case of previous chemotherapy, with no difference related to previous chemotherapy exposure. In total there were 13 pregnancies and 8 births in 7 patients. LIMITATIONS, REASONS FOR CAUTION: The pathology in the two groups of patients was not comparable. In the group of patients who had chemotherapy before OTC, there were 95% of hematological malignancies. In the group of patients who did not have chemotherapy before OTC only 1 out of 9 patients had a malignant hematological disease while 44% had some pathology affecting the ovaries. Few women are available for study and only large changes are likely to have statistical significance. WIDER IMPLICATIONS OF THE FINDINGS: These results suggest that prior cancer chemotherapy should no longer be considered a limitation to cryopreservation of ovarian tissue and current recommendations in this regard should be revised. STUDY FUNDING/COMPETING INTEREST(S): This study was supported by the Agence de la Biomédecine (France's biomedical office). There are no competing interests to report. TRIAL REGISTRATION NUMBER: NCT02184806.

Neoadjuvant chemotherapy (NACT) increases immune infiltration and programmed death-ligand 1 (PD-L1) expression in epithelial ovarian cancer (EOC).

Background: Lymphocytic infiltration at diagnosis is prognostic in EOC, however, the impact of NACT on tumour infiltrating lymphocytes (TILs) or PD-L1 expression remains poorly described. Patients and methods: Patients with EOC and sequential samples (pre-NACT, post-NACT or relapse) were retrospectively identified. TILs were evaluated on whole sections; stromal TILs (sTILs) scored as percentage of stromal area with high sTILs defined as ≥50%; intra-epithelial TILs (ieTILs) scored semi-quantitatively (0-3) with high ieTILs ≥2. A smaller number were available for PD-L1 evaluation, cut-off for positivity was ≥5% staining. Results: sTILs were detected in all tumours at diagnosis (range 2-90%, median 20%), with 22% (25/113) showing high sTILs. Among evaluable paired pre/post-NACT samples (N = 83), an overall increase in median sTILs from 20% to 30% was seen following NACT (P = 0.0005); individually the impact of NACT varied with sTILs increasing in 51% (42/83), decreasing in 25%, and stable in 24%. Post-NACT sTILs were predictive of platinum-free interval (PFI), patients with PFI ≥6 months had significantly higher post-NACT sTILs (sTILs 28% versus 18% for PFI <6 months, P = 0.026); pre-NACT sTILS were not predictive. At diagnosis, 23% showed high ieTILs, and following NACT 33% showed increasing ieTILs. Proportion of tumours with PD-L1-positive immune cells was 30% (15/50) pre-NACT and 53% (27/51) post-NACT (P = 0.026). Among paired tumours, 63% of PD-L1-negative tumours became positive after NACT, furthermore cisplatin induced PD-L1 expression in PD-L1-negative EOC cell lines. On multivariate analysis, high sTILs both pre- and post-NACT were independent prognostic factors for progression-free survival (PFS) (HR 0.49, P = 0.02 and HR 0.60, P = 0.05, respectively). No prognostic impact of ieTILs or PD-L1 expression was detected. Conclusions: In EOC, sTILs levels are prognostic at diagnosis and remain prognostic after NACT. TILs and PD-L1 expression increase following NACT. Evaluation of immune parameters in the post-NACT tumour may help select patients for immunotherapy trials.

Networking for ovarian rare tumors: a significant breakthrough improving disease management.

BACKGROUND: Rare ovarian tumors represent >20% of all ovarian cancers. Given the rarity of these tumors, natural history, prognostic factors are not clearly identified. The extreme variability of patients (age, histological subtypes, stage) induces multiple and complex therapeutic strategies. METHODS: Since 2011, a national network with a dedicated system for referral, up to 22 regional and three national reference centers (RC) has been supported by the French National Cancer Institute (INCa). The network aims to prospectively monitor the management of rare ovarian tumors and provide an equal access to medical expertise and innovative treatments to all French patients through a dedicated website, www.ovaire-rare.org. RESULTS: Over a 5-year activity, 4612 patients have been included. Patients' inclusions increased from 553 in 2011 to 1202 in 2015. Expert pathology review and patients' files discussion in dedicated multidisciplinary tumor boards increased from 166 cases in 2011 (25%) to 538 (45%) in 2015. Pathology review consistently modified the medical strategy in 5-9% every year. The rate of patients' files discussed in RC similarly increased from 294 (53%) to 789 (66%). An increasing number (357 in 5 years) of gynecologic (non-ovarian) rare tumors were also registered by physicians seeking for pathological or medical advice from expert tumor boards. CONCLUSION: Such a nation-wide organization for rare gynecological tumors has invaluable benefits, not only for patients, but also for epidemiological, clinical and biological research.

Reassessing the clinical spectrum associated with hereditary leiomyomatosis and renal cell carcinoma syndrome in French FH mutation carriers.

We addressed uncertainties regarding hereditary leiomyomatosis and renal cell carcinoma (HLRCC) by exploring all French cases, representing the largest series to date. Fumarate hydratase (FH) germline testing was performed with Sanger sequencing and qPCR/MLPA. Enzyme activity was measured when necessary. We carried out whenever possible a pathology review of RCC and S-(2-succino)-cysteine (2SC)/fumarate hydratase immunohistochemistry. We estimated survival using non-parametric Kaplan-Meier. There were 182 cases from 114 families. Thirty-seven RCC were diagnosed in 34 carriers (19%) at a median age of 40. Among the 23 RCC with pathology review, 13 were papillary type 2. There were 4 papillary RCC of unspecified type, 3 unclassified, 2 tubulocystic, and 1 collecting duct (CD) RCC, all 2SC+ and most (8/10) FH-. Of the remaining 14, papillary type 2, papillary unspecified, CD, and clear cell histologies were reported. The vast majority of RCC (82%) were metastatic at diagnosis or rapidly became metastatic. Median survival for metastatic disease was 18 months (95%CI: 11-29). 133 cases (73%) had a history of cutaneous leiomyomas, 3 developed skin leiomyosarcoma. Uterine leiomyomas were frequent in women (77%), but no sarcomas were observed. Only 2 cases had pheochromocytomas/paraganglioma. CONCLUSION: Our findings have direct implications regarding the identification and management of HLRCC patients.

Multidisciplinary management of advanced ovarian cancer for an optimal therapeutic strategy.

The management of advanced ovarian cancer generally requires specialist multidisciplinary teamwork to achieve optimum outcomes. Preoperative computed tomography scans are the imaging modality of choice in determining the extent of disease and aiding in surgical planning. Histological classification is crucial to define various subtypes with their different behaviour and prognosis and to plan the best therapeutic strategy. Pathological prognostic factors, such as histological type, degree of differentiation, and FIGO stage must be described. To determine the ability to optimally cytoreduce advanced ovarian cancer, an experienced gynaecological oncologist needs to explore the entire upper abdomen and the pelvic and para-aortic lymph node regions to define the peritoneal cancer index (PCI). The final assessment is the completeness of cytoreduction (CC) score which is important in predicting prognosis and decision of post-surgical surgery. Ovarian cancer is the leading cause of death from gynaecologic cancers. Initial management is best provided by a specialist multidisciplinary team, including a radiologist, a pathologist, a gynaecologic oncologist, and a medical oncologist.

Cytomorphology of ovarian clear cell carcinomas in peritoneal effusions.

OBJECTIVE: To investigate and describe the cytomorphology of malignant effusions from ovarian clear cell carcinomas (OCCC). METHODS: Five cases of malignant peritoneal effusions from OCCC histologically confirmed were analysed and compared. RESULTS: Among the malignant peritoneal effusions exhibiting clear cell features, a characteristic feature of OCCC was the presence of large deposits of a hyaline matrix. This matrix may be typically arranged either in 'raspberry bodies' or 'globule-like' structures. Other rare neoplasms composed of clear cells must be considered in the differential diagnosis such as yolk sac tumour of the ovary, clear cell subtype of endometrial carcinoma and, less frequently, malignant peritoneal mesothelioma as well as metastatic renal cell carcinoma. CONCLUSIONS: Ovarian clear cell carcinomas have distinct morphological features that are helpful in making a cytological diagnosis of this entity. The role of cytological examination in ovarian neoplasms is of paramount importance, as stated by The International Federation of Gynecology and Obstetrics (FIGO) recommendations.

Growing teratoma syndrome of the ovary presenting with liver metastasis: report of a case.

Growing teratoma syndrome (GTS) is a rare condition among patients with non-seminomatous germ cell tumors who present with enlarging metastatic masses during appropriate systemic chemotherapy in the context of normalized serum markers. This is an infrequent event in the progression of testicular tumors, and is even less common in the case of ovarian germ cell tumors. The pathogenesis of GTS is not completely understood and diagnosis can only be made with certainty after complete pathologic examination. Although histologically benign, GTS may present an enveloping growth with aggressive local expansion, which can be related to substantial morbidity and mortality. Surgery is the only recommended treatment and early recognition of this syndrome is essential as it offers hope for curative resection and avoids the use of ineffective chemotherapy. The authors present a brief review of the literature, along with the case report of a 37-year-old woman presenting GTS with liver involvement who was successfully treated by debulking surgery followed by major liver resection. This report demonstrates that complete surgical resection results in excellent disease control. More importantly, it highlights that clinicians need to be aware of the possible development of GTS when monitoring their patients with non-seminomatous germ cell tumors. These patients require coordinated care between oncologist, gynecologists, and general surgeons to obtain the best possible outcomes.

[Molecular-integrated risk profile: An opportunity for therapeutic de-escalation in intermediate and high-intermediate risk endometrial cancer]. / Cancer de l'endomètre de stade localisé : la perspective d'une désescalade thérapeutique guidée par la classification moléculaire.

In Europe, endometrial cancer is the fourth most common cancer among women. The majority of patients are diagnosed at a localized stage. For these patients, the standard of care is based on an hysterectomy with salpingo oophorectomy±lymph node staging. Through the assessment of histopathologic features, risk groups are determined: low, intermediate, high-intermediate, and high risk. Adjuvant strategies are guided by these risk groups. While the prognosis of low-risk and high-risk is well known, that of intermediate and high-intermediate risk is more heterogeneous, and the therapeutic index of adjuvant treatments is more questionable. Several trials (PORTEC [Post Operative Radiation Therapy in Endometrial Carcinoma] I, GOG [Gynecologic Oncology Group] 99, ASTEC [A Study in the Treatment of Endometrial Cancer] EN.5, PORTEC II, Sorbe et al trial) have assessed observation, vaginal cuff brachytherapy and/or pelvic external beam radiotherapy in this population. Vaginal cuff brachytherapy reduces the local recurrence rate, and pelvic external beam radiotherapy the pelvic recurrence rate. However, no benefit in terms of overall survival or occurrence of distant metastases is highlighted. Compared to observation, brachytherapy and above all external beam radiotherapy are associated with an increased morbidity, and with a decreased quality of life. In order to improve the therapeutic ratio and to optimize medico-economic decisions, therapeutic de-escalation strategies, based on the molecular profiles, are emerging in clinical trials, and in the recommendations for the management of intermediate and high-intermediate risk endometrial cancers. The four main molecular profiles highlighted by the genomic analyzes of The Cancer Genome Atlas (TCGA) - POLE (polymerase epsilon) mutation, non-specific molecular profile, MMR (MisMatch repair) deficiency, and p53 mutation - but also the quantification of lymphovascular space invasion (absent, focal or substantial), and the assessment of L1CAM (L1 cell adhesion molecule) overexpression represent growing concerns. Thus, the use of molecular-integrated risk profile to determine the best adjuvant treatment represent a major way to personalize adjuvant treatment of endometrial cancers, with therapeutic de-escalation opportunity for around half of the high-intermediate risks. However, in the absence of prospective data, inclusion in clinical trials assessing molecular profile-based treatment remains the best therapeutic opportunity.

[Fertility preservation in cervical cancer, analysis of 30 years of practice and immersion in future developments]. / La préservation de fertilité en cas de cancer du col, analyse de 30 ans de pratique et immersion dans les évolutions à venir.

OBJECTIVES: The strategy of fertility preservation (FP) in cervical cancer has been challenged for several years and a therapeutic de-escalation seems to be necessary. In this context, we evaluated the oncological, fertility and obstetric outcomes of surgical techniques performed in our centre for FP. METHODS: This retrospective uni centric trial included 75 patients, managed at the Gustave Roussy Institute between 1995 and 2020, for cervical cancer (stage IB1 FIGO 2018) and having conducted a fertility preservation project after a complete pre-therapy work-up. The objective of this study was to understand our results on fertility and obstetrical outcomes and to correlate them with oncological data and finally to evaluate the evolution of our surgical practices. RESULTS: 54 patients benefited from an extended trachelectomy and no lymph node involvement was found. 1 patient received a complementary treatment postoperatively which did not allow to preserve her fertility. The recurrence rate was 4.8% (4/75) with one death described. 31 pregnancies were obtained, representing a pregnancy rate of 50%. 74% of pregnancies were obtained spontaneously and 60% of pregnancies were carried to term. CONCLUSION: Our results are similar to those in the literature. Despite a fertility preservation project, only half of the patients were able to achieve a pregnancy.

[Precision medicine and immuno-radiotherapy]. / Médecine de précision et immunoradiothérapie.

Numerous clinical studies aim to integrate immunotherapy in radiotherapy oncology, either for generating abscopal responses in metastatic patients in combination with radiotherapy, or in the treatment of a locally advanced tumor. The search for biomarkers of response to treatment is a major axis in the development of these therapeutic combinations, to allow the early identification of patients who will benefit from the treatment, in the context of an increasingly personalized approach. We review some of the strategies that can be applied for personalization to combined radiotherapy and immunotherapy treatments.

Glassy cell carcinoma of the uterine cervix: 20-year experience from a comprehensive cancer center.

PURPOSE: Glassy cell carcinoma (GCC) of the uterine cervix is a rare entity. This study aims at describing the clinical characteristics and outcomes of cervical GCC patients treated in a comprehensive cancer center. MATERIAL AND METHODS: We retrospectively reported patients and tumors characteristics, therapeutic management, overall survival (OS), progression-free progression (PFS), relapse rates, and toxicities. RESULTS: Between 1994 and 2014, 55 patients were treated with curative intent. The median age at diagnosis was 41 years (range, 20-68). Among 22 patients with early stage tumors (IA2-IB1-IIA1), 17 had preoperative brachytherapy, followed by radical hysterectomy. Among 33 patients with locally advanced disease (≥IB2), 32 underwent chemoradiation±brachytherapy boost. After a median follow-up of 5.4 years (range, 0.15-21.7 years), 18/55 (33%) patients experienced tumor relapse. Local recurrence occurred in 2/22 (9%) patients with early disease (treated with upfront surgery) and in 3/32 (9%) patients with locally advanced disease. Most frequent relapses were distant, occurring in a total of 11/55 patients (20%). PFS rates at 5-year were 86.4% (95% CI: 63.4-95.4) for early stage versus 75.9% (95% CI: 55.2-89.2) for locally advanced stages, respectively (P=0.18). CONCLUSION: Large cohort data are warranted to guide the optimal management of GCC. From this retrospective analysis, a multimodal approach yielded to good disease control in early stages tumors. Given the high-risk of distant failure, consideration should be given to adjuvant chemotherapy in locally advanced disease.

Evaluation of adjuvant vaginal vault brachytherapy in early stage cervical cancer patients.

PURPOSE: Adjuvant external beam radiotherapy (EBRT) was shown to decrease pelvic relapses in patients with an early stage cervical cancer and intermediate-risk histopathological prognostic factors, at the cost of increased bowel morbidity. We examined the feasibility and results of adjuvant brachytherapy alone as an alternative to EBRT in this situation. PATIENTS AND METHODS: Medical records of consecutive patients receiving adjuvant brachytherapy between 1991 and 2018 for an early stage cervical cancer were examined. Patients were included if they presented a pT1a2N0 or pT1b1N0 disease following radical colpohysterectomy. Adjuvant vaginal wall brachytherapy (without EBRT) was indicated because of a tumor size≥2cm and/or presence of lymphovascular space invasion (LVSI). Patients received 60Gy to 5mm of the vaginal wall, through low-dose or pulse-dose rate technique. Patients' outcome was examined for disease control, toxicities and prognostic factors. RESULTS: A total of 40 patients were included. Eight patients (20%) had LVSI, 26 patients (65%) had a tumor size≥2cm. With median follow-up time of 42.0 months, 90% of patients were in complete remission and four patients (10%) experienced tumor relapse, all in the peritoneal cavity, and associated with synchronous pelvic lymph node failure in 2/4 patients. No vaginal or isolated pelvic nodal failure was reported. At 5 year, overall survival was 83.6% (CI95%: 67.8-100%) and disease-free survival was 85.1% (CI95%: 72.6-99.9%). In univariate analysis, probability of relapse correlated with tumor size≥3cm (P=0.004). No acute or late toxicity grade more than 2 was reported. CONCLUSION: Brachytherapy alone was a well-tolerated adjuvant treatment for selected patients with intermediate risk factors. The risk of relapse in patients with tumor size≥3cm was however high, suggesting that EBRT is more appropriate in this situation.

Feasibility of ovarian cryopreservation in borderline ovarian tumours.

BACKGROUND: Borderline ovarian tumours (BOT) do not exhibit overt stromal invasion and are less aggressive than invasive epithelial ovarian tumours. BOT also arise in younger patients than those who develop epithelial ovarian tumours. Our aim was to evaluate the feasibility of ovarian cryopreservation (OC) in patients treated for BOT. METHODS: A retrospective study of data concerning young patients (less than 35 years of age) who underwent surgery for a BOT with OC planned during the surgical procedure. RESULTS: Twenty-three patients, treated between January 2002 and February 2008, were initially selected but six of them were excluded from the present study (four because the tumour was malignant and two because it was benign). Finally, 17 patients were diagnosed as having BOT based on the frozen section analysis. In nine (53%) of these cases, OC was finally performed. In eight cases, OC was not performed; instead, in four cases a simple cystectomy was finally performed (one patient was in fact pregnant at the time of surgery), in one case malignant disease was found and in three (18%) patients OC was not technically feasible because no normal ovarian parenchyma was evident on gross inspection. CONCLUSION: In patients treated for a BOT, OC was eventually feasible in 53% of patients in whom this procedure was initially planned. In 18%, this procedure was aborted because no macroscopic healthy ovarian tissue could be found.

[Combined flow cytometry determination of S-phase fraction and DNA ploidy is an independent prognostic factor in node-negative invasive breast carcinoma: review of a series of 271 patients with stage I and II breast cancer]. / L'évaluation conjointe du contenu en ADN et de la fraction de cellules en phase S est un paramètre pronostique indépendant dans les cancers du sein de stades I et II.

PURPOSE: To assess the significance of S-phase fraction (SPF) and DNA ploidy evaluated by DNA flow cytometry as prognostic markers in stage I or II breast cancer. PATIENTS AND METHODS: A series of 271 patients, treated by surgery, radiotherapy+/-systemic therapy was analysed (median follow up: 64 months). Standardized flow cytometry cell preparation from frozen samples and consensus rules for data interpretation were followed. Three SPF classes were defined on the basis of tertiles after adjustment for ploidy. Four groups were defined based on combinations of DNA ploidy (DIP: diploid; ANEUP: aneuploid) and SPF: DIP and low SPF (DL, N=37), DIP and medium or high SPF (DMH, N=76), ANEUP and low SPF (AL, N=24), ANEUP and medium or high SPF (AMH, N=68). Local control rate (LCR), disease-free survival (DFS), metastasis-free survival (MFS), and overall survival (OS) were correlated with DNA ploidy, SPF, DL to AMH groups, T and N stages, SBR grading, age, and hormonal status on univariate and multivariate analysis (Cox model). RESULTS: On univariate analysis, DFS and LCR were higher for DIP tumours. High SPF values were associated with shorter DFS. LCR, MFS, DFS, and OS rates were significantly different with an increasingly poorer prognosis from DL to AMH. On multivariate analysis, groups DL to AMH, histological node involvement and T stage were independently associated with MFS, and DFS. In N- patients, DL to AMH remained independent for MFS and DFS. For SBR III tumours, MFS and OS were significantly different in DL to AMH groups. These results strongly support the use of combined evaluation of DNA ploidy and SPF as independent parameters in clinical trials for N- stage I and II breast cancer.

[Ovarian tissue cryopreservation for prepubertal girls: indications and feasibility]. / Cryoconservation de cortex ovarien chez la fille prépubère: indications et faisabilité.

OBJECTIVE: Survival improvement of children, adolescents and young women with cancer has led to consider with more cautiousness the long time iatrogenic side effects of treatments. Among those, premature ovarian failure has been described even for children. The aim of the study was to evaluate the indications and the feasibility of ovarian tissue cryopreservation for prepubertal girls. PATIENTS AND METHODS: From September 2000 to December 2004, 47 prepubertal girls were referred by oncologists for ovarian tissue cryopreservation. After informed consent, the ovarian tissue was collected and frozen by a slow cooling protocol until the temperature of liquid nitrogen. A histological analysis and a follicular account were performed. RESULTS: The harvest of ovarian tissue was performed for 45 patients. No surgical side effect occurred. The younger girls had a follicular density higher than the older. No metastatic ovarian tumour was found. DISCUSSION AND CONCLUSIONS: Numerous arguments as the follicular density in the ovary, the age of the patient, no surgical side effect, no metastatic ovarian tumour and recent progress in term of birth after ovarian tissue autografting allowed to think it is very important and ethical to propose an ovarian tissue cryopreservation even for children before sterilising treatment.

A mesocolic leiomyosarcoma metastatic to the breast: case report and review of the literature.

This report describes a patient with mesocolic leiomyosarcoma, initially treated by excisional surgery. One year later the patient developed breast and hepatic metastases. To our knowledge, metastasis of leiomyosarcoma to the breast has not been previously reported in the literature. The discussion covers unusual sites for metastases of primary leiomyosarcomas and those tumors that most commonly give rise to breast metastases. Certain rare primary tumors of the breast related to the family of sarcomas are also brought to the attention of the reader. These may or may not have malignant characteristics. In the light of the differences in prognosis and treatment, recognition and precise diagnosis is of importance.

Comparison of the prognostic value of Scarff-Bloom-Richardson and Nottingham histological grades in a series of 825 cases of breast cancer: major importance of the mitotic count as a component of both grading systems.

The most commonly used system in Europe for breast carcinoma was developed by Scarff, Bloom and Richardson (SBR). It was recently modified by Elston and Ellis and significant improvement in reproducibility has been shown by using precise grading guidelines. This study investigated whether the use of this new grade (defined as the Nottingham grade, NG) would improve the prognostic stratification of patients. The respective prognostic value of the two grading schemes was compared in a retrospective series of 825 patients uniformly treated for a small invasive breast carcinoma and followed for a median of 6 years. Univariate and multivariate analysis showed that both histological grades were strongly correlated to overall and metastasis free survival. We have separately analysed the prognostic value of each of the three components used to assess the two grading systems and found that the mitotic index was the only significant prognostic factor for 5 year survival. Univariate analysis showed the count to be more discriminant in the NG scheme (p = 0.0006) than in the SBR scheme (p = 0.04). However, in univariate and multivariate analysis, the prognostic value of the global NG was not significantly better than SBR grade. This may be related, in part, to an uneven distribution of cases reflected by a much lower number of cases with a high mitotic index in the NG system (2%) than in the SBR system (10%). Our study emphasizes the importance of the mitotic count in assessing the prognosis of breast cancers and indicates that the factors which condition this count (tissue processing, microscopic observation, threshold) must be well standardized and controlled.
