RESUMO

Triple-negative breast cancer (TNBC) is a specific subtype of breast cancer lacking hormone receptor expression and HER2 gene amplification. TNBC represents a heterogeneous subtype of breast cancer, characterized by poor prognosis, high invasiveness, high metastatic potential, and a tendency to relapse. In this review, the specific molecular subtypes and pathological aspects of triple-negative breast cancer are illustrated, with particular attention to the biomarker characteristics of TNBC, namely: regulators of cell proliferation and migration and angiogenesis, apoptosis-regulating proteins, regulators of DNA damage response, immune checkpoints, and epigenetic modifications. This paper also focuses on omics approaches to exploring TNBC, such as genomics to identify cancer-specific mutations, epigenomics to identify altered epigenetic landscapes in cancer cells, and transcriptomics to explore differential mRNA and protein expression. Moreover, updated neoadjuvant treatments for TNBC are also mentioned, underlining the role of immunotherapy and novel and targeted agents in the treatment of TNBC.

RESUMO

Cutaneous squamous cell carcinomas are very rare in children. The recommended treatment for localized cancers is surgery with sufficient margins which can sometimes be mutilating especially for facial localizations. We report a rare case of facial skin carcinoma in a 13-year-old girl measuring 3 cm in diameter infiltrating the tip of the nose. The treatment was an exclusive external radiation therapy with a dose of 70 Gy in 35 fractions in standard fractionation. The technique used was intensity-modulated conformational radiotherapy. It was proposed as an alternative to surgery which could be mutilating. A complete tumour response was obtained with a good aesthetic result and without major toxicity.

RESUMO

In patients with locally advanced rectal cancer, neoadjuvant radiotherapy or chemoradiotherapy followed by total mesorectal excision as a standard of care. We aimed to explore the number, size, germinal centers, extracapsular invasion of lymph nodes (LN), and their impact on overall survival and disease free survival. Furthermore we also investigated the characteristics of lymph nodes in patients who received neoadjuvant therapy and those who underwent surgery between 2011 and 2018. The count and measurement of lymph nodes was assessed by careful visual inspection and manual palpation. The predictive cut-off value of the lymph node ratio (LNR) was determined based on the receiver operating characteristic (ROC), method and the survival outcomes based on Kaplan-Meier curves. We found that the size and the number of lymph nodes decreased significantly after neoadjuvant treatment. The mean LN for patients who received neoadjuvant therapy was 12.68 ± 6.69 and for patients who did not receive neoadjuvant therapy was 16.29 ± 5.61 (P = .012). The average size for patients who received neoadjuvant therapy followed by surgery was 3.30 ± 1.10 versus 4.22 ± 1.18 mm for control group (surgery only) (P < .001), an LNR of 0.13 (sensitivity: 86%, specificity: 47%, AUC: 60%, 95% CI, 0.41%-0.76%) predicted recurrence and metastasis. Presence of lymph nodes with germinal centers was significantly associated with absence of vascular invasion, nodal tumor deposits, distant metastasis, and lower age group (<50 years). However there was no association seen between overall survival and relapse free, total number of lymph nodes enlarged and extracapsular invasion in positive nodes. Finally there is no association between lymph nodes with germinal centers and tumor response after neoadjuvant treatment in locally advanced rectal cancer.

RESUMO

Background: Soft tissue sarcomas (STS) are a heterogeneous group of tumors. For adequate therapeutic management, an accurate diagnosis is necessary. In Morocco, the diagnosis is essentially based on the morphological and immunohistochemical study. Compared to other techniques, fluorescence in situ hybridization (FISH) is easier to develop and less expensive. This study aims to assess the feasibility and utility of implementing FISH technique to improve diagnostic accuracy and establish a good classification. Material and methods: This is a retrospective cohort study. 211 cases of mesenchymal tumors were included. Hematoxylin Eosin Safran (HES) staining was performed in all cases followed by immunohistochemistry (IHC). FISH was performed in all cases with suspected STS. The probes used were EWSR1, MDM2 and SS18. The performance of FISH and histopathological test were evaluated by the ROC curve method (receiver operating characteristic). We evaluated the concordance between FISH and real time PCR by Cohen test. Results: The real-time PCR technique showed good agreement with the FISH test by a Kappa coefficient of 60% (p = 0.035). FISH was able to confirm that it is more accurate (Youden's Index = 91%) than histological/immunohistochemical analysis (Youden's Index = 51%), as well as the positive predictive value was higher (100%) with an ROC curve finding a larger area under the curve of 0.953 (95% CI: 0.918-0.988), p = 0.000 which supports that FISH shows high performance to present an accurate final diagnosis. Conclusion: This is the first and the largest Moroccan series for the molecular diagnosis of STS by FISH. Our study shows that paraffin FISH is a sensitive and specific ancillary tool in the diagnosis of STS when used in the appropriate clinicopathological context.

RESUMO

Background: Giant cell tumors (GCTs) are locally aggressive but rarely malignant bone neoplasms that uncommonly involve the skull. In this report, we describe a tumor of the sphenoid sinus. Case presentation: A 51-year-old female was presented with headache, and bilateral decreased visual acuity, CT scan, and brain MRI revealed an infra-sellar enhancing tumor expanding to the sellar and supra-sellar region which proved to be a GCT. the patient had received 03 months of preoperative denosumab-based treatment and imaging follow-up showed regression in size and morphology modifications of tumor tissue. Conclusion: This is one of few reports to describe the appearance of sphenoid bone GCT, and the first report to highlight the effects of short-term denosumab treatment in GCTb in such a location.

RESUMO

The esthesioneuroblastoma (ENB) is a rare malignant sinonasal tumor of neuroectodermal origin. This study aimed to improve the understanding of the clinical features by reviewing the literature and analyzing the medical records of patients diagnosed with ENB in our institution between 2012 and 2019. A total of 6 cases of ENB were available for analysis. The mean age at the time of diagnosis was 36 years. The main complaints at presentation were the rhinologic signs. Tumors were classified as stage C of Kadisk in 3 cases and stage D in the others. According to TNM (modified by Dulguerov), 2 patients were T3N0M0, one T4N0M0, one T3N1M0, and two T4N1M0. The diagnosis of ENB was based on pathological examination. According to Hyams histological grading, low-grade lesions (Hyams I and II) were seen in 2 cases, high-grade undifferentiated lesions (Hyams III and IV) were seen in 4. Of the 6 patients, 4 received surgery. The surgical approaches mainly included an endoscopic endonasal resection in 2 cases, a cranial-facial resection surgery in 1 case, and an expanded endoscopic endonasal approach in combination with craniotomy in 1 case. Four patients received adjuvant radiotherapy (RT). RT dose ranged from 60 to 70 Gy. A total of 3 patients had lymph node metastasis and received RT of the neck. Chemotherapy was delivered in 2 patients. After a mean follow-up of 4.5 years, 4 patients were free of recurrence. Unfortunately, 1 patient died from a progressive disease 6 months after RT. ENB is a rare locally aggressive tumor of the nasosinusal cavities. The first-line treatment for resectable tumors should include primary surgical resection with adjuvant RT. However, this tumor remains of poor prognosis. Therefore, long-term close follow-up based on symptoms, endoscopy, and imaging is essential.

RESUMO

Purpose: Caregivers in radiation oncology are exposed to a high risk of burnout which sometimes causes serious consequences for their health, which can in turn affect patient care. In this study, we investigated the prevalence of burnout and its psychological impact on health professionals and determined the factors that predispose to the risk of burnout. Methods and materials: A cross-sectional survey was conducted with descriptive and analytical purposes among the different teams within the oncology and radiotherapy departments in different hospitals (CHU and regional hospitals) in Morocco, through an online self-questionnaire composed of sociodemographic data, professional data, working conditions, an assessment of interfering factors, the Maslach Burnout Inventory (MBI), the Generalised Anxiety Disorder-7 (GAD-7) scale and the Patient Health Questionnaire-9 (PHQ-9) scale. Results: One hundred and eighteen caregivers participated in this evaluation. 62.7% were physicians, 75.4% worked in university hospitals and 53.4% were in radiotherapy departments. Analysis of the three dimensions of the Maslach Burnout Inventory - Human Services Survey (MBI-HSS) score found high scores in the dimensions of emotional exhaustion (81.4%) and depersonalisation (79.7%), and low scores in decreased personal accomplishment (46.6%). The evaluation of the impacts of burnout in the latter found a mean of the Patient Health Questionnaire-9 (PHQ-9) at 12.45 + 7.84 and the mean of the GAD-7 at 9.73 + 5.98. Conclusion: Our results are in line with those found in the literature, hence the need for screening and active prevention of burnout among radiation oncology caregivers.

RESUMO

Stereotactic MR-guided Radiotherapy (MRgRT) is an interesting treatment option for adrenal gland metastases (AGM). We reviewed data from 12 consecutive patients treated with MRgRT for an AGM in our center between 14 November 2019 and 17 August 2021. Endpoints were tolerance assessment, the impact of adaptive treatment on target volume coverage and organs at risk (OAR) sparing, local control (LC), and overall survival (OS). The majority of patients were oligometastatic (58.3%), with 6 right AGM, 5 left AGM and 1 left and right AGM. The prescribed dose was 35 to 50 Gy in 3 to 5 fractions. The median PTV V95% on the initial plan was 95.74%. The median V95% of the PTVoptimized (PTVopt) on the initial plan was 95.26%. Thirty-eight (69%) fractions were adapted. The PTV coverage was significantly improved for adapted plans compared to predicted plans (median PTV V95% increased from 89.85% to 91.17%, p = 0.0478). The plan adaptation also significantly reduced Dmax for the stomach and small intestine. The treatment was well tolerated with no grade > 2 toxicities. With a median follow-up of 15.5 months, the 1−year LC and OS rate were 100% and 91.7%. Six patients (50%) presented a metastatic progression, and one patient (8.3%) died of metastatic evolution during the follow-up. Adaptation of the treatment plan improved the overall dosimetric quality of MRI-guided radiotherapy. A longer follow-up is required to assess late toxicities and clinical results.

RESUMO

Soft-tissue sarcomas are malignant tumors that require good management within specialized centers. Our study aims to assess the benefit of handling these kinds of tumors using the Multidisciplinary Meeting (MDM) approach. The current paper details this approach through a prospective study that has lasted for 42 months in the HASSAN II University Hospital Center, Fez, Morocco. During this research work, 116 cases were selected with an average age of 53 years. In 95.7% of the cases, it was found that the lower limb was the most frequent tumor type (78.4%). Also, ninety-two (92) patients (79.3%) have had a prior biopsy. Ninety-nine (99) patients (85.3%) have received a magnetic resonance imaging scan (MRI) before surgery. Sixty-three (63) patients were operated on, including R0 resection used for 37 patients, R1 used for 21 patients, and R2 used for five patients. As a result, liposarcomas were the most frequent type (30.1%), followed by synovial sarcomas (14.6%), leiomyosarcomas (9.5%), ewing sarcoma (8.6), and undifferentiated pleomorphic sarcomas (7.7%). In addition, neoadjuvant chemotherapy was used for 36 patients. The other 22 patients received adjuvant chemotherapy and/or radiotherapy. The overall survival rate was 60.56 months, which proves a significant improvement, thanks to the multidisciplinary meeting approach. Conclusion. The conducted investigation has shown that using MDM for managing soft-tissue sarcomas of extremities improves the patients' survival rate. Moreover, results have proven MDM might allow optimal treatment regarding less local recurrence and metastasis.

RESUMO

We report here the case of a patient admitted for management of posterior fossa cerebral hemangioblastoma. A 16-year-old male patient with a history of intracranial hypertension syndrome consisting of progressively worsening headache, vomiting, especially morning and jet vomiting, and decreased visual acuity. The patient's symptomatology worsened a few days later with the appearance of a disturbance of balance with enlargement of the sustentation polygon. The patient initially benefited from a brain computed tomography (CT) scan that objectified a solidocystic process of the posterior brain fossa. The patient then underwent a surgical excision that was considered partial and the diagnosis of hemangioblastoma was made on the surgical specimen. Since the surgical removal was partial the patient was referred to our training where he received external radiotherapy on his hemangioblastoma of the posterior brain fossa. The patient was examined one month after the end of irradiation; he presented a spectacular improvement in his neurological symptomatology with a clear regression of balance disorders. The standard treatment for cerebellar hemangioblastoma is complete microsurgical removal, but our results show a high level of efficacy for fractional photon radiotherapy after partial surgery of this benign tumour.

RESUMO

We report the case of a patient with recurrent pterygo-palatal angiofibroma and its treatment. A 21-year-old male patient had a long history of recurrent epistaxis with progressive nasal obstruction. He was diagnosed with an angiofibroma centered in the right pterygo-palatine fossa. Initially, he underwent surgical excision with removal of the entire tumor. The evolution was clinically good with no signs of recurrence on the cervico-facial scan of control (CT). Nine months after, he presented a reappearance of epistaxis. A cervico-facial MRI was performed and showed a recurrence of the tumor process, which this time was considered inextirpable, hence the decision to opt for radiotherapy with intensity modulated radiation therapy (IMRT). He has improved clinically with a clear reduction in tumor mass on CT scan. This technique represents an interesting alternative to overcome anatomical complexity of the region, cover the tumor and preserve the organs at risk.

RESUMO

Prognosis for patients with locally advanced rectal cancer remains controversial. The purpose of this study was to elucidate possible association between therapeutic effect on lymph nodes (LNs) and patient prognosis. Overall, 149 patients with rectal cancer received preoperative radiotherapy in concomitance with chemotherapy or exclusive radiotherapy before rectal excision. Microscopic examination of formalin-fixed lymph nodes was assessed for therapeutic effect. The establishment of groups combined reaction tissue types of fibrosis, colloid, and necrosis after neoadjuvant treatment was assigned. The average age was 56.38 years, ranged between 22 and 88 years, 53% were female, and 47% were men, with a sex ratio of 1 : 12. In the present study, we noticed that after a median follow-up time of 40.67 months (0-83; SD: 21.1), overall survival was statistically significant depending on age groups. Kaplan-Meier analysis showed significant differences in the rate of patients with an age under 65 years (70.64%) versus those with an age over 85 years (36.5%) (p < 0.001). Also, the OS was statistically significant depending on therapeutic effect groups composed of 0TE (No Therapeutic effect), C+ (presence of only colloidal effect), F+ (presence of only fibrosis tissue), and ME+ (mixture of 2 or 3 types of therapeutic effect) group. Indeed, we observed a significantly higher OS rate in the ME + group (86%) compared with the OS rate of LNs group with no therapeutic effect (57%) (p=0.028). Additionally, there was a significant association between the presence of fibrosis on LNs and an extended delay of more than 8 weeks to neoadjuvant treatment completion and surgery. Our study indicates that the best patient prognosis could be predicted based on tumor presenting a best pathologic effect on lymph nodes, and that delaying surgery for more than 8 weeks to neoadjuvant treatment completion improves therapeutic response on LNs.

RESUMO

Pathologic features depending on tumor response to preoperative chemoradiotherapy are important to determine the outcomes in patients with rectal cancer. Evaluating the potential predictive roles of biomarker expression and their prognostic impact is a promising challenge. We reported here the immunohistochemical staining of a panel marker of mismatch repair protein (MMR), Ki67, HER-2, and p53. Additionally, identification of somatic mutations of KRAS, NRAS, and BRAF genes were performed by direct sequencing and pyrosequencing in pretreated biopsy tissues from 57 patients diagnosed for rectal cancer. Clinical features and pathological criteria for postneoadjuvant treatment surgical resection specimen's data were collected. Immunohistochemical expression and mutational status were correlated with therapeutic response, overall survival, and disease progression. The mean age of patients was 56 years. Seven (12.3%) out of 57 patients had a complete therapeutic response. Our analysis showed that when using complete therapeutic response (Dworak 4) and incomplete therapeutic response (Dworak 3, 2, and 1) as grouping factor, high p53 expression at the pretreatment biopsy was significantly associated to an incomplete response (p = 0.002). For 20 and 2 out of 57, KRAS and NRAS mutations were detected, respectively. The majority of these mutations affected codon 12. KRAS mutations detected at codon 146 (A146T, A146V) was associated with the appearance of recurrence and distant metastasis (p = 0.019). A high expression of HER-2 corresponding to score 3+ was observed in 3 pretreatment biopsy specimens. This class was significantly associated with a short relapse-free survival (p = 0.002). Furthermore, the high expression of Ki67 was moderately correlated with an older age (p = 0.016, r = 0.319). In addition, this shows that high p53 expression in the pretreatment biopsy was associated with an incomplete response in surgical resection specimens after neoadjuvant treatment, and a HER-2 score 3+ can be a predictive factor of distant metastasis and local recurrence. Larger, prospective, and more studies are needed.

RESUMO

In this paper, we report a case of primary squamous cell carcinoma of the endometrium (PSCCE) with a literature review. A 64-year-old woman was admitted because of postmenopausal bleeding. The gynecological exam found bleeding from the endocervix. The pelvic ultrasound objectified uterine regular contours, endometrial thickened was 10 mm, the presence of an intra cavitary lesion measuring 56/70 mm. The diagnostic hysteroscopy revealed a whitish appearance taking all the uterine cavity making evoke a tumor of the endometrium. Pelvic MRI showed a tumor limited to the uterine corpus endometrium (invasion by more than 50% of the myometrium) without invasion of the cervix. Radical hysterectomy, bilateral salpingo-oophorectomy, and lymph nodes dissection were performed. Grossly, the endometrial carcinoma was polypoid tumor occupying the entire uterine cavity. Histologically, the diagnosis of SCC was retained. No adenocarcinoma element was recognized. Neither squamous metaplasia nor dysplasia was recognized. No ectopic cervical tissue was found. The SCC was found to invade into deeper one half of the myometrium. No tumor cells were seen in other sites including the cervix, ovaries, parameters, and lymph nodes. The patients was FIGO 2009 stage IB (pT1B, N0), and was treated with adjuvant radiation. The patient had a disease progression in the pelvis 3 months after the irradiation. We reported a case of PSCCE which can help to enrich the literature for the treatment and prognosis of this disease.

RESUMO

NK/T-cell lymphoma is a severe and rare disorder in Africa and in Europe. Treatment is based on radiotherapy and chemotherapy. We here report two cases of elderly patients aged 55 years and 52 years, respectively, with bilateral nasal obstruction associated with purulent rhinorrhea. Clinical examination showed cleft palate. Diagnosis was made on the basis of immunohistochemical examination of biopsies. Both patients underwent CHOEP chemotherapy followed by radiotherapy. Nasal NK/T-cell lymphoma is an aggressive type of non-Hodgkin's lymphoma with specific clinicopathologic features. Combining chemotherapy with radiotherapy in patients with advanced stage of the disease does not seem to improve survival compared with radiotherapy alone, which is the treatment of choice especially for localized stages. Nasal NK/T-cell lymphoma is rare. Diagnosis is based on immunohistochemical examination. Treatment includes chemotherapy and radiotherapy. This lymphoma has a poor overall prognosis, even with appropriate therapy.

RESUMO

Malignant Hodgkin's lymphoma or (Hodgkin's disease) accounts for only 10% of all lymphomas but it is one of the most commonly diagnosed sub-types of lymphoma during pregnancy. This is due, in large part, to the maximum of disease incidence which coincides with reproductive age. The management of a pregnant patient with Hodgkin's disease requires multidisciplinary approach as well as effective communication with the patient and her family. The aim is to optimize mother's chances of being cured while ensuring the delivery of a healthy baby. We here report the rare case of a pregnant patient with Hodgkin's disease at 17 weeks of amenorrhea.

RESUMO

This study aimed to investigate the epidemiological, clinical, therapeutic and evolutionary features of undifferentiated carcinoma of the nasopharynx in adults. We conducted a retrospective cohort study of 163 patients aged 17 years old and over, treated for non metastatic undifferentiated carcinoma of the nasopharynx. The average age of our patients was 46,5 years, with a sex-ratio of 1.7; 35.57% of patients had locally advanced tumors (T3-T4) and 52.27% had advanced regional lymph nodes involvement (N2-N3). Neoadjuvante chemotherapy was performed in 77% of patients and 93.8% of patients underwent concomitant radiochemotherapy. After a mean follow-up interval of 40.8 months overall survival was 92.9% and relapse-free survival (RFS) was 78.9%. Relapse-free survival was caculated according to different prognostic factors, revealing a statistically significant difference based on lymph nodes involvement; three-year RFS rates were 88%, 82.6%, 80.8% and 61.5% in patients with tumor classified as N0, N1, N2 and N3, respectively (p = 0.02). Nasopharyngeal cancer is a complex disease, but progress has been made thanks to advances in radiotherapy and molecular biology. Concomitant radiochemotherapy is the therapeutic standard for patients with clinical stage greater than or equal to T2, or greater than or equal to N1. The innovative techniques in radiation therapy appear promising and they could reduce late toxicity while ensuring an excellent local control rate.

RESUMO

The extraskeletal myxoid chondrosarcoma (CME) is a rare malignant soft tissue tumour described as a distinct clinical, histological, immunohistochemical, genetical and evolutive entity. It represents only 2.5% of soft tissue sarcomas. Its individualization is important because it has a long and indolent clinical course, and tumour-related death often occurs after a long survival period. The diagnostic key is morphological supported by immunohistochemistry and genetics t (9; 22) that allow differentiating it from other tumours with myxoid stroma and from chordoma. This report describes a patient with paravertebral extraskeletal myxoid chondrosrcoma with a high locoregional extension.

RESUMO

The finding on imaging (computed tomography scan or magnetic resonance imaging) of synchronous malignant renal mass in patient with an active nonrenal malignancy without renal specific symptoms is not frequent and diagnostic evaluation can be challenging. We describe a 54-year-old Moroccan male former chronic smoker who presented to our hospital with dry cough and impairment of the performance status. The imaging found a tumor mass in the left upper lobe of the lung associated to mediastinal lymph node and a scanno-guided biopsy of this tumor showed a non small cell lung cancer. The radiological staging revealed a solitary renal mass in the right kidney. The patient received firstly two cycles of a lung cancer chemotherapy with a partial response in the lung and a stability of the renal mass. Consequently, he underwent a scanno-guided biopsy of this mass which confirmed a synchronous clear cell renal carcinoma. The patient got chemo radiotherapy for the lung cancer and then after that he got a partial nephrectomy. He is still under a good control with more than 2 years after the initial diagnosis.
