TP73 is a member of the TP53 gene family and produces N- and C-terminal protein isoforms through alternative promoters, alternative translation initiation and alternative splicing. Most notably, p73 protein isoforms may either contain a p53-like transactivation domain (TAp73 isoforms) or lack this domain (ΔTAp73 isoforms) and these variants have opposing or independent functions. To date, there is a lack of well-characterised isoform-specific p73 antibodies. Here, we produced polyclonal and monoclonal antibodies to N-terminal p73 variants and the C-terminal p73α isoform, the most common variant in human tissues. These reagents show that TAp73 is a marker of multiciliated epithelial cells, while ΔTAp73 is a marker of non-proliferative basal/reserve cells in squamous epithelium. We were unable to detect ΔNp73 variant proteins, in keeping with recent data that this is a minor form in human tissues. Most cervical squamous cell carcinomas (79%) express p73α, and the distribution of staining in basal cells correlated with lower tumour grade. TAp73 was found in 17% of these tumours, with a random distribution and no association with clinicopathological features. These data indicate roles for ΔTAp73 in maintaining a non-proliferative state of undifferentiated squamous epithelial cells and for TAp73 in the production of differentiated multiciliated cells.

Karcinom děložního čípku je jednou z nejčastějších malignit zjištěných v průběhu těhotenství. Většina případů je zjištěna v časném stadiu onemocnění. Časná diagnostika se opírá o screeningové vyšetření v I. trimestru těhotenství. Vzhledem k těhotenským změnám na děložním hrdle jsou nálezy obtížně hodnotitelné, s tendencí k falešné pozitivitě. Péče o pacientku a plod by měla být v rukách multidisciplinárního týmu s individualizovanou léčbou a s respektováním přání pacientky. Placenta accreta je nejčastějším typem abnormálně invazivní placenty (AIP). Ultrazvukové vyšetření má své nezastupitelné místo zejména v časné diagnostice abnormální invaze trofoblastu. Mezi hlavní rizikové faktory abnormální nidace patří císařský řez v anamnéze (nebo jiné předchozí operace na děloze, kyretáž) a vyšší věk matky.

Carcinoma of the uterine cervix is the most frequent malignant disease diagnosed in pregnant women. Most cases are early carcinomas due to cervical screening methods (PAPP smear, HPV DNA testation and colposcopy). However sometimes the results of the examination are unclear due to the physiological pregnancy associated changes of the cervical epithelium (squamous of the vaginal portion and columnar of the cervical canal). Cervical cancer complicating pregnancy is a specific clinical situation, that requires individual approach, multidisciplinary experienced team of specialists in gynaecological oncology and in obstetrics, respecting the opinion of the pregnant woman. Placenta accreta represents the most frequent type of abnormally adherent placenta, where placental villi are attached to the myometrium. Placenta accreta may be ultrasonically diagnosed antepartum. The main etiological factors are previous caesarean section scar (or other previous uterine incisions, uterine curettage) and older age of pregnant women.

I přes rozpoznanou etiopatogenezi, primární prevenci a národní screeningový program zůstává pokročilý a metastatický cervikální karcinom (CC) významným klinickým problémem s limitovanými možnostmi léčebného ovlivnění. Imunoterapeutika - checkpoint inhibitory vstupují do léčebného portfolia u pacientek s inoperabilními lokálně pokročilými stadii a u pacientek s progredujícím, metastatickým a rekurentním cervikálním karcinomem. Přinášejí potřebnou naději v kohortě křehkých obtížně léčitelných pacientek. Včlenění imunoterapie v kombinaci s chemoterapií s nebo bez bevacizumabu do první linie systémové léčby a v monoterapii v druhé linii léčby navazující na chemoterapii založené na platině vedlo k signifikantnímu prodloužení celkového přežítí pacientek s CC.

Despite the identified etiopathogenesis, primary prevention and national screening program, advanced and metastatic cervical cancer remains a significant clinical problem with limited treatment options. Immunotherapeutics - checkpoint inhibitors enter the treatment portfolio in patients with inoperable locally advanced stages and bring the necessary hope in patients with progressive, metastatic and recurrent cervical cancer in the cohort of fragile, difficult-to-treat patients. The inclusion of immunotherapy in combination with chemotherapy with or without bevacizumab in first-line systemic therapy and in second-line therapy monotherapy following platinum-based chemotherapy resulted in a significant prolongation of overall survival of patients with CC.

Recentní literární zdroje uvádějí, že přibližně 15–20 % všech maligních onemocnění má virovou etiologii, z toho asi 5 % způsobují lidské papilomaviry. Přítomnost a perzistence rizikových typů papilomavirovů je jedním z nejsilnějších rizikových faktorů pro vznik cervikální dysplazie a posléze zhoubného nádoru. Předkládaná práce poskytuje stručný přehled a charakteristiku rizikových faktorů, které ovlivňují spontánní a postintervenční regresi a perzistenci papilomavirové infekce v oblasti děložního čípku.

Recent literature sources suggest that 15–20% of all malignant diseases have a viral aetiology. About 5% of these are caused by the human papillomavirus. The presence of papillomavirus is one of the strongest risk factors for development of a cervical pre-cancerous lesion and subsequent cervical cancer. The presented review provides a brief summary and characterisation of risk factors that influence spontaneous and post-interventional regression and persistence of papillomavirus in the cervical area.

After the publication of the Laparoscopic Approach to Cervical Cancer (LACC) trial, open surgery has become the standard approach for radical hysterectomy in early stage cervical cancer. Recent studies assessed the role of a non-radical approach in low risk cervical cancer and showed no survival difference compared with radical hysterectomy. However, there is a gap in knowledge regarding the oncologic outcomes of minimally invasive simple hysterectomy in low risk cervical cancer. This review offers an overview of the current evidence on the role of the minimally invasive approach in low risk cervical cancer and raises the need for a new clinical trial in this setting.

OBJECTIVE: Patients with TNM T1a cervical cancer have excellent prognosis; however, the risk for recurrence remains an issue of concern and management guidelines are based on limited data. Here we performed subgroup analysis of the Surveillance in Cervical Cancer (SCCAN) consortium with the objective of defining the prognosis of T1a cervical cancer patients. METHODS: SCCAN was an international, multicentric, retrospective cohort study of patients with cervical cancer undergoing surgical treatment in tertiary centers. Inclusion criteria included: histologically confirmed cervical cancer treated between 2007 and 2016; TNM T1a; primary surgical management; and at least 1-year of follow-up data availability. Exclusion criteria included treatment with primary chemo-radiation, and missing treatment-related or clinical data. RESULTS: Out of 975 patients included, 554 (57 %) were T1a1 and 421 (43 %) T1a2. The majority had squamous-cell carcinoma (78 %). 79 patients (8.1 %) had lymphovascular space invasion (LVSI). 455 patients (47 %) underwent radical hysterectomy/ parametrectomy. Laparoscopic and open surgery was performed in 401 (41 %) and in 361 (37 %) patients, respectively. Adjuvant treatment was administered to 56 patients (5.7 %). Assessment of lymph nodes (LN) was performed in 524 patients (54 %), with LN involvement found in 15 (2.9 %). There were 40 (4.1 %) recurrences, occurring at a median of 26 months (4-106), out of which 33 (82.5 %) occurred in pelvis. Among T1a1 cases, there were 10 recurrences (2.0 %) if LVSI was negative, and 3 recurrences (6.7 %) if LVSI was positive. Among T1a2 cases, there were 23 recurrences (6.7 %) if LVSI was negative, and 4 recurrences (5.1 %) if LVSI was positive. There were 3 recurrences in the LN+ group (recurrence rate 20 %). CONCLUSIONS: The risk of recurrence in T1a cervical cancer was 4.1 % corresponding to the rates seen in patients with FIGO 1B cancer in recently published prospective trials. LN involvement represents a risk factor for disease recurrence. Our results indicate that stage T1a cervical cancer, apart from T1a1 LVSI negative disease, should follow the same principles in the management as that of FIGO stage 1B cancer.

OBJECTIVE: The substantial material and legislative investments in establishing and maintaining cytological screening in the Czech Republic represent barriers to a direct transition to primary HPV screening. Therefore, the LIBUSE project was implemented to test the efficacy of phasing in HPV DNA testing as a co-test to cytology in routine screening of women >30 years of age. METHODS: Women aged 30 to 60 years who underwent regular annual Pap smears were co-tested for HPV DNA with selective 16/18 genotyping at 3-year intervals. All HPV 16/18-positive cases and/or cases with a severe abnormality in cytology were sent for colposcopy; HPV non-16/18-positive cases and LSILs were graded using p16/Ki67 dual-stain cytology, and positive cases were sent for colposcopy. RESULTS: Overall, 2409 patients were included. After the first combined screening (year 'zero') visit, 7.4% of women were HPV-positive and 2.0% were HPV16/18-positive; only 8 women had severe Pap smear abnormalities. Triage by dual staining was positive in 21.9% of cases (28/128). Biopsy confirmed 34 high-grade precancer lesions. At the second combined visit (year 'three'), the frequency of HPV infection (5.3% vs. 7.4%) frequency of HPV16/18 (1.1% vs. 2.0%), referrals for colposcopy (35 vs. 83), and biopsy verified high-grade lesions (5 vs. 34) were significantly lower (all P ≤ 0.001). CONCLUSION: The addition of HPV DNA testing with selective genotyping of HPV16/18 to existing cytology screening significantly increased the safety of the program. The gradual introduction of HPV testing was well received by healthcare professionals and patients, and can facilitate transformation of the cytology-based screening.

BACKGROUND: At the first interim analysis of the phase 3 ENGOT-cx11/GOG-3047/KEYNOTE-A18 study, the addition of pembrolizumab to chemoradiotherapy provided a statistically significant and clinically meaningful improvement in progression-free survival in patients with locally advanced cervical cancer. We report the overall survival results from the second interim analysis of this study. METHODS: Eligible patients with newly diagnosed, high-risk (FIGO 2014 stage IB2-IIB with node-positive disease or stage III-IVA regardless of nodal status), locally advanced, histologically confirmed, squamous cell carcinoma, adenocarcinoma, or adenosquamous cervical cancer were randomly assigned 1:1 to receive five cycles of pembrolizumab (200 mg) or placebo every 3 weeks with concurrent chemoradiotherapy, followed by 15 cycles of pembrolizumab (400 mg) or placebo every 6 weeks. Pembrolizumab or placebo and cisplatin were administered intravenously. Patients were stratified at randomisation by planned external beam radiotherapy type (intensity-modulated radiotherapy [IMRT] or volumetric-modulated arc therapy [VMAT] vs non-IMRT or non-VMAT), cervical cancer stage at screening (FIGO 2014 stage IB2-IIB node positive vs III-IVA), and planned total radiotherapy (external beam radiotherapy plus brachytherapy) dose (<70 Gy vs ≥70 Gy [equivalent dose of 2 Gy]). Primary endpoints were progression-free survival per RECIST 1.1 by investigator or by histopathological confirmation of suspected disease progression and overall survival defined as the time from randomisation to death due to any cause. Safety was a secondary endpoint. FINDINGS: Between June 9, 2020, and Dec 15, 2022, 1060 patients at 176 sites in 30 countries across Asia, Australia, Europe, North America, and South America were randomly assigned to treatment, with 529 patients in the pembrolizumab-chemoradiotherapy group and 531 patients in the placebo-chemoradiotherapy group. At the protocol-specified second interim analysis (data cutoff Jan 8, 2024), median follow-up was 29·9 months (IQR 23·3-34·3). Median overall survival was not reached in either group; 36-month overall survival was 82·6% (95% CI 78·4-86·1) in the pembrolizumab-chemoradiotherapy group and 74·8% (70·1-78·8) in the placebo-chemoradiotherapy group. The hazard ratio for death was 0·67 (95% CI 0·50-0·90; p=0·0040), meeting the protocol-specified primary objective. 413 (78%) of 528 patients in the pembrolizumab-chemoradiotherapy group and 371 (70%) of 530 in the placebo-chemoradiotherapy group had a grade 3 or higher adverse event, with anaemia, white blood cell count decreased, and neutrophil count decreased being the most common adverse events. Potentially immune-mediated adverse events occurred in 206 (39%) of 528 patients in the pembrolizumab-chemoradiotherapy group and 90 (17%) of 530 patients in the placebo-chemoradiotherapy group. This study is registered with ClinicalTrials.gov, NCT04221945. INTERPRETATION: Pembrolizumab plus chemoradiotherapy significantly improved overall survival in patients with locally advanced cervical cancer These data, together with results from the first interim analysis, support this immuno-chemoradiotherapy strategy as a new standard of care for this population.

AIM: The aim of this study was to assess whether the use of sentinel lymph node (SLN) in addition to lymphadenectomy was associated with survival benefit in patients with early-stage cervical cancer. METHODS: International, multicenter, retrospective study. INCLUSION CRITERIA: cervical cancer treated between 01/2007 and 12/2016 by surgery only; squamous cell carcinoma, adenocarcinoma, adenosquamous carcinoma, FIGO 2009 stage IB1-IIA2, negative surgical margins, and laparotomy approach. Patients undergoing neo-adjuvant and/or adjuvant treatment and/or with positive para-aortic lymph nodes, were excluded. Women with positive pelvic nodes who refused adjuvant treatment, were included. Lymph node assessment was performed by SLN (with ultrastaging protocol) plus pelvic lymphadenectomy ('SLN' group) or pelvic lymphadenectomy alone ('non-SLN' group). RESULTS: 1083 patients were included: 300 (27.7 %) in SLN and 783 (72.3 %) in non-SLN group. 77 (7.1 %) patients had recurrence (N = 11, 3.7 % SLN versus N = 66, 8.4 % non-SLN, p = 0.005) and 34 (3.1 %) (N = 4, 1.3 % SLN versus N = 30, 3.8 % non-SLN, p = 0.033) died. SLN group had better 5-year disease-free survival (DFS) (96.0 %,95 %CI:93.5-98.5 versus 92.0 %,95 %CI:90.0-94.0; p = 0.024). No 5-year overall survival (OS) difference was shown (98.4 %,95 %CI:96.8-99.9 versus 96.8 %,95 %CI:95.4-98.2; p = 0.160). SLN biopsy and lower stage were independent factors associated with improved DFS (HR:0.505,95 %CI:0.266-0.959, p = 0.037 and HR:2.703,95 %CI:1.389-5.261, p = 0.003, respectively). Incidence of pelvic central recurrences was higher in the non-SLN group (1.7 % versus 4.5 %, p = 0.039). CONCLUSION: Adding SLN biopsy to pelvic lymphadenectomy was associated with lower recurrence and death rate and improved 5-year DFS. This might be explained by the lower rate of missed nodal metastasis thanks to the use of SLN ultrastaging. SLN biopsy should be recommended in patients with early-stage cervical cancer.
