Unsolved Issues in the Integrated Histo-Molecular Classification of Endometrial Carcinoma and Therapeutic Implications.

Endometrial carcinoma (EC) is the most frequent gynecological cancer, with an increasing incidence and mortality in recent times. The last decade has represented a true revolution with the development of the integrated histo-molecular classification of EC, which allows for the stratification of patients with morphologically indistinguishable disease into groups with different prognoses. Particularly, the POLE-mutated subgroup exhibits outstanding survival.

Weekly Paclitaxel for Pregnancy Associated Breast Cancer.

Background: Pregnancy associated breast cancer is the most common cancer diagnosed during pregnancy. When chemotherapy is indicated, although it is more common to use anthracycline-based chemotherapy as a first treatment, we suggest weekly paclitaxel as a valid alternative both in the adjuvant and neoadjuvant setting, as this allows for weekly assessment of maternal-fetal well-being and a quicker maternal and fetal bone marrow recovery in cases of unexpected preterm delivery.

Patients And Methods: We present a case series of pregnant breast cancer patients treated with weekly paclitaxel between 2016 and 2022.

Reproductive outcomes after conservative treatment in early and advanced stage MOGCTs.

Background: Malignant ovarian germ cell tumors usually occur in young women. The standard of care is fertility sparing surgery and comprehensive surgical staging followed by adjuvant chemotherapy with BEP (bleomycin, etoposide, cisplatin) if needed. The aim of this study was to analyze the reproductive outcomes after conservative treatment in patients diagnosed, treated and followed up in MITO (Multicenter Italian Trials in Ovarian Cancer) centers.

Spontaneous and induced abortions in women with a diagnosis of gestational related neoplasm: a population-based linkage study in Lombardy, 2010-2020.

Background: A diagnosis of cancer during pregnancy or within one year after the end of pregnancy is a major clinical and public health issue. The current study aimed at estimating the incidence of pregnancy-associated cancer (PAC) and assessing whether the risk of abortion is increased in women diagnosed with cancer.

Methods: This population-based cohort study used the regional healthcare utilization (HCU) databases of Lombardy, the largest region in Italy, to identify the women who delivered between 2010 and 2020.

Immune microenvironment dynamics in breast cancer during pregnancy: impact of gestational age on tumor-infiltrating lymphocytes and prognosis.

Background: Breast cancer during pregnancy (PrBC) is a rare condition known for its aggressive clinical behavior. The presence of tumor-infiltrating lymphocytes (TILs) has been shown to have a significant impact on the prognosis of these patients. Despite some biological characteristics of the tumor that may differ depending on the gestational age, little is known about the dynamics of the immune landscape within the tumor microenvironment (TME) in PrBC.

Breast Cancer during Pregnancy as a Special Type of Early-Onset Breast Cancer: Analysis of the Tumor Immune Microenvironment and Risk Profiles.

Breast cancer during pregnancy (PrBC) is a rare tumor with only a little information on its immune landscape. Here, we sought to characterize the cellular composition of the tumor microenvironment (TME) of PrBC and identify its differences from early-onset breast cancer (EOBC) in non-pregnant women. A total of 83 PrBC and 89 EOBC were selected from our Institutional registry and subjected to tumor-infiltrating lymphocytes (TILs) profiling and immunohistochemistry for CD4, CD8, forkhead box P3 (FOXP3), and programmed death-ligand 1 (PD-L1) (clone 22C3).

Surveillance alone in stage I malignant ovarian germ cell tumors: a MITO (Multicenter Italian Trials in Ovarian cancer) prospective observational study.

Objective: The aim of this study was to analyze the oncological outcome of stage I malignant ovarian germ cell tumors patients included in the MITO-9 study to identify those who might be recommended routine surveillance alone after complete surgical staging.

Methods: MITO-9 was a prospective observational study analyzing data collected between January 2013 and December 2019. Three groups were identified: group A included 13 patients stage IA dysgerminoma and IAG1 immature teratoma; group B included 29 patients with stage IB-C dysgerminomas, IA-C G2-G3 immature teratomas and stage IA mixed malignant ovarian germ cell tumors and yolk sac tumors; and group C included five patients (two patients with stage IC1 and one patient with stage IC2 yolk sac tumors and two patients with mixed-stage IC2 malignant ovarian germ cell tumors).

[Formula: see text]Long-term neurodevelopmental outcome after prenatal exposure to maternal hematological malignancies with or without cytotoxic treatment.

Data on the long-term neurodevelopmental outcomes of children exposed to hematological maternal cancer with or without treatment during pregnancy are lacking. A total of 57 children, of whom 33 males and 24 females, prenatally exposed to hematological malignancies and its treatment, were invited for neuropsychological and physical examinations at 18 months, 36 months, 6, 9, 12, 15 and 18 years of age. Oncological, obstetrical, neonatal and follow-up data of these children were collected.

"Lights and Shadows": An Interpretative Phenomenological Analysis of the Lived Experience of Being Diagnosed With Breast Cancer During Pregnancy.

Cancer diagnosed during pregnancy is a rare event. The most common type of malignancy diagnosed in pregnant women is breast cancer, whose incidence is expected to raise in the next future due to delayed childbirth, as well as to the increased occurrence of the disease at young age. Pregnant women diagnosed with breast cancer are exposed to multiple sources of stress, which may lead to poorer obstetric outcomes, such as preterm birth and low birth weight.

Stage I juvenile granulosa cell tumors of the ovary: A multicentre analysis from the MITO-9 study.

Objective: Juvenile type granulosa cell tumor (JGCTs) are extremely rare, mainly diagnosed in young women and pre-pubertal girls at stage I disease. Literature is scanty and guidelines regarding the optimal management are still controversial. The aim of this study is to add on the experience of the MITO group (Multicenter Italian Trials in Ovarian Cancer).

Obstetric and neonatal outcomes in women with pregnancy associated cancer: a population-based study in Lombardy, Northern Italy.

Background: Pregnancy associated cancer (PAC) may lead to adverse obstetric and neonatal outcomes. This study aims to assess the association between PACs and adverse perinatal outcomes [i.e.

Can we replace adjuvant chemotherapy with surveillance for stage IA-C immature ovarian teratomas of any grade? an international multicenter analysis.

Background: The role of surveillance after surgery for stage IA-C grade 2 (G2) or grade 3 (G3) immature teratomas (ITs) is controversial with many guidelines advocating adjuvant chemotherapy. Here, we investigate the safety of surveillance in stage IA-C G1-3 ITs.

Methods: Clinicopathological data were analysed on postpubertal patients with stage I pure ITs in Multicenter Italian Trials in Ovarian Cancer centres and at Charing Cross Hospital, UK, between January 1985 and January 2018.

Chemotherapy for breast cancer during pregnancy induces vascular alterations and impaired development of placental villi: A preliminary histopathological study.

Objective: To evaluate histological alterations in placentas of women affected by breast cancer and treated with chemotherapy during pregnancy.

Study Design: We retrospectively reviewed histological slides of 23 placentas of patients affected by breast cancer and treated with chemotherapy during pregnancy and 23 control placentas of women without breast cancer and with physiological pregnancies of the same gestational age.

Results: All the patients had breast ductal infiltrating carcinoma, 19 of 23 cases had a G3 cancer.

Sharing real-world experiences to optimize the management of olaparib toxicities: a practical guidance from an Italian expert panel.

Olaparib is the first poly(ADP-ribose) polymerase inhibitor approved as maintenance therapy of recurrent ovarian cancer (OC) patients with a BRCA mutation. To achieve the maximum clinical benefit, adherence to olaparib must be persistent. However, in clinical practice, this is challenged by the frequent suboptimal management of toxicities.
