RESUMO
In a variety of cancers, immune checkpoint inhibitors (ICIs) have demonstrated substantial survival advantages. Nevertheless, the widespread use of ICIs in the clinic has resulted in a growing interest in immune-related adverse events (irAEs) and their treatment methods. This paper reports a case in which a patient with three sequential severe irAEs was successfully treated. After undergoing two regimens of sintilimab in conjunction with chemotherapy for advanced lung cancer, the patient developed myocarditis combined with hepatitis. Subsequently, the patient developed pneumonia following remission from treatment. We also discuss the mechanism of irAEs, principles of treatment, and progress in the study of biomarkers for early prediction of irAEs by reviewing the literature.
RESUMO
BACKGROUND: Several studies have shown that the survival outcomes of chemoradiotherapy (CRT) are not inferior to surgery alone in patients with esophageal squamous cell carcinoma (ESCC). This study aimed to compare survival outcomes of ESCC treated with immunochemotherapy (ICT) followed by surgery or definitive CRT and to explore subgroups of patients who could benefit from one treatment strategy. METHODS: Pooled data were obtained from two prospectively registered clinical trials of patients with ESCC at the Affiliated Cancer Hospital of Nanjing Medical University. One trial involved treatment with neoadjuvant ICT followed by surgery, while the other involved induction ICT followed by definitive CRT. To balance potential biases, we conducted an overlap weighting (OW) analysis to compare the rates of 2-year progression-free survival (PFS), locoregional relapse-free survival (LRRFS), distant relapse-free survival (DRFS), and overall survival (OS). Additionally, propensity score matching (PSM) was performed to analyze failure pattern. RESULTS: The median follow-up time of the survivors was 39.3 months. After overlap weighting, the rates of 2-year PFS, LRRFS, DRFS, and OS for patients undergoing surgery and CRT were 61.5 % and 59.7 %, 67.2 % and 69.9 %, 81.3 % and 90.7 %, 84.6 % and 79.1 %, respectively (P>.05 for all). A trend for improved 2-year OS was observed in the surgery group in patients who did not respond to ICT (P=.07). CONCLUSION: The differences in the rates of 2-year PFS, LRRFS, DRFS, and OS between the surgery group and the chemoradiotherapy group did not reach statistical significance.
RESUMO
Several immune related adverse events (irAEs) were reported with the wide application of immune checkpoint inhibitors (ICIs) in tumors. ICI-related skin reactions are the most common, which are manifested as maculopapules, rash, pruritus, vitiligo, psoriasis, and lichenoid rash.Among them, the incidence of pruritus is second only to maculopapule/rash, but both often co-exist. The severity of pruritus is mostly mild to moderate and can be relieved after symptomatic treatment with antihistamines. Symptoms are slightly relieved after conventional treatment in patients with severe pruritus, but it easily recurs and eventually develops into refractory pruritus.The patient's quality of life may be affected and may also be life-threatening. We report a case of a patient with postoperative recurrence of gallbladder neuroendocrine carcinoma,who developed refractory pruritus after sintilimab use, which was relieved after naloxone infusion after unsuccessful conventional drug therapy. By analyzing the treatment plan of this typical case of immune-related refractory pruritus after using sintilimab, this report discusses how clinical pharmacists can provide individualized treatment of patients by using their expertise and clinicians' cooperation and complementation in treating clinically difficult cases. This case report may be used as a reference in treating patients with refractory pruritus after the clinical use of sintilimab.
RESUMO
Thymic carcinoma (TC) is an uncommon type of thymic epithelial tumors. Patients with relapsed or refractory TCs have a poor prognosis. Immune checkpoint inhibitor monotherapy can be applied as a second-line treatment for such cases. This study reported a TC patient who did not respond to conventional chemotherapy and radiotherapy but achieved prolonged partial remission lasting 17 months following the third-line treatment with anti-programmed cell death-1 inhibitor sintilimab. This patient did not experience any serious side effects associated with sintilimab treatment. The above results demonstrated that sintilimab could be a feasible therapeutic option for refractory TC patients.
RESUMO
BACKGROUND: The combination of targeted therapy and immunotherapy has improved the clinical outcomes of unresectable hepatocellular Carcinoma (HCC). However, the overall prognosis remains suboptimal. This study aims to evaluate the efficacy and safety of a novel combination of radiofrequency ablation (RFA) with lenvatinib plus sintilimab in unresectable HCC. METHODS: In this retrospective study, patients diagnosed with unresectable HCC were included and divided into two cohorts: RFA combined with lenvatinib plus sintilimab (R-L-S group) and lenvatinib plus sintilimab (L-S group). The primary efficacy endpoints were objective response rate (ORR) and progression free survival (PFS). Adverse events were analyzed to assess the safety profiles. RESULTS: The median follow-up periods for the entire cohort were 14.0 months. The R-L-S group (n = 60) had a significantly higher ORR than those with L-S alone (n = 62) (40.0% vs. 20.9%; p = 0.022). Moreover, patients in the R-L-S group had improved median PFS (12 vs. 8 months; p = 0.013) and median overall survival (24 vs. 18 months; p = 0.037), as compared with lenvatinib and sintilimab alone. No significant difference in treatment related adverse event (TRAE) of any grade between the two groups. The most common TRAEs of grade ≥ 3 were fatigue 10.0% (6/60) and hand-foot skin reaction 10.0% (6/60) in the R-L-S group and hand-foot skin reaction 11.3% (7/62) in the L-S group. CONCLUSION: In unresectable HCC patients, the incorporation of RFA to lenvatinib plus sintilimab demonstrated improved efficacy without compromising safety compared with lenvatinib plus sintilimab alone.

Background: As one of the most common types of primary bone sarcomas in adolescents and young adults, osteosarcoma has a high probability of local invasion and distant metastasis with a poor prognosis. Case Presentation: Here, we report the case of a 34-year-old patient with advanced metastatic osteosarcoma. Considering the high expression of PD-L1 and the inability of the patient to tolerate chemotherapy, anti-PD-1 antibody (sintilimab 200 mg, q3w) and anti-angiogenesis drug (anlotinib 8 mg D1-14, q3w) were administered. The metastatic lesions were treated with local radiotherapy. The patient obtained an 11.7-month-sustained remission period, and he also enjoyed a better quality of life. Conclusion: This case demonstrates that sintilimab plus anlotinib may be a feasible treatment regimen for osteosarcoma patients.
RESUMO
Objective: Both camrelizumab plus paclitaxel and carboplatin (CTC) and sintilimab plus gemcitabine and cisplatin or carboplatin (SGP) have been approved by the National Medical Products Administration of China (NMPA) for the first-line treatment of local advanced or metastatic sqNSCLC. However, the comparison of the two treatments as first-line treatments in efficacy or pharmacoeconomics has barely been studied. To deeply understand the costs and outcomes of the two treatments, this work directly compared the cost-effectiveness for the first-line treatment of local advanced or metastatic squamous NSCLC in the Chinese mainland. Methods: A network meta-analysis was first performed based on the three clinical trials, namely, CameL-Sq, ORIENT-12, and C-TONG1002, to compare the clinical benefits of the two treatments. The Weibull approximation was applied to further calculate the life expectancy of the two treatments. The partitioned survival model (PSM) was next established, and one-way sensitivity analysis and probabilistic sensitivity analysis were also performed to evaluate the stability of the underlying parameter values and assumptions within the model. Results: CTC treatment gained 0.68 QALYs and cost $14,764. SGP treatment gained 0.54 QALYs and cost $14,584. The CTC arm gained 0.14 additional QALYs and cost $179 more than the SGP arm, and the ICERs was $1,269/QALY, which was lower than one-fold GDP per capita in the Chinese mainland ($12,734 GDP per capita in 2022). In probabilistic sensitivity analysis, when the WTP ranged from $12,734-38,202 (1-3 folds, 2022 GDP per capita in China), the CTC group had higher probabilities than the SGP group for being cost effective, which ranged from 85.65% to 88.38%. Conclusion: From the perspective of the payers, camrelizumab plus chemotherapy was cost-effective compared with sintilimab plus chemotherapy for the first-line treatment of local advanced or metastatic squamous NSCLC in the Chinese mainland.
RESUMO
BACKGROUND: Pancreatic adenocarcinoma, a malignancy that arises in the cells of the pancreas, is a devastating disease with unclear etiology and often poor prognosis. Locally advanced pancreatic cancer, a stage where the tumor has grown significantly but has not yet spread to distant organs, presents unique challenges in treatment. This article aims to discuss the current strategies, challenges, and future directions in the management of locally advanced pancreatic adenocarcinoma (LAPC). AIM: To investigate the feasibility and efficacy of programmed cell death 1 (PD-1) inhibitor sintilimab plus concurrent chemoradiotherapy for LAPC. METHODS: Eligible patients had LAPC, an Eastern cooperative oncology group performance status of 0 or 1, adequate organ and marrow functions, and no prior anticancer therapy. In the observation group, participants received intravenous sintilimab 200 mg once every 3 wk, and received concurrent chemoradiotherapy (concurrent conventional fractionated radiotherapy with doses planning target volume 50.4 Gy and gross tumor volume 60 Gy in 28 fractions and oral S-1 40 mg/m2 twice daily on days 1-14 of a 21-d cycle and intravenous gemcitabine 1000 mg/m2 on days 1 and 8 of a 21-d cycle for eight cycles until disease progression, death, or unacceptable toxicity). In the control group, participants only received concurrent chemoradiotherapy. From April 2020 to November 2021, 64 participants were finally enrolled with 34 in the observation group and 30 in the control group. RESULTS: Thirty-four patients completed the scheduled course of chemoradiotherapy, while 32 (94.1%) received sintilimab plus concurrent chemoradiotherapy with 2 patients discontinuing sintilimab in the observation group. Thirty patients completed the scheduled course of chemoradiotherapy in the control group. Based on the Response Evaluation Criteria in Solid Tumors guidelines, the analysis of the observation group revealed that a partial response was observed in 11 patients (32.4%), stable disease was evident in 19 patients (55.9%), and 4 patients (11.8%) experienced progressive disease; a partial response was observed in 6 (20.0%) patients, stable disease in 18 (60%), and progressive disease in 6 (20%) in the control group. The major toxic effects were leukopenia and nausea. The incidence of severe adverse events (AEs) (grade 3 or 4) was 26.5% (9/34) in the observation group and 23.3% (7/30) in the control group. There were no treatment-related deaths. The observation group demonstrated a significantly longer median overall survival (22.1 mo compared to 15.8 mo) (P < 0.05) and progression-free survival (12.2 mo vs 10.1 mo) (P < 0.05) in comparison to the control group. The occurrence of severe AEs did not exhibit a statistically significant difference between the observation group and the control group (P > 0.05). CONCLUSION: Sintilimab plus concurrent chemoradiotherapy was effective and safe for LAPC patients, and warrants further investigation.
RESUMO
Primary pulmonary malignant peripheral nerve sheath tumor (MPNST) is a rare soft tissue sarcoma with a low incidence, poor prognosis and limited treatment options. The present study reported a case of lung MPNST in a 63-year-old male patient without any pulmonary symptoms. Immunohistochemical analysis of the tumor indicated a programmed death-ligand 1 (PD-L1) expression tumor proportion score of 60%. A total of six courses of sintilimab were used in this patient and a remarkable response was achieved. In summary, sintilimab single-agent immunotherapy may be a novel treatment for pulmonary MPNST. When encountering analogous cases in the future, oncologists can test for the expression of PD-L1 in patients to guide the therapy's design.
RESUMO
Purpose: As one of the most important breakthroughs in cancer therapy, immune checkpoint inhibitors have greatly prolonged survival of patients with breast cancer. However, their application and efficacy are limited, especially for advanced HER2-negative breast cancer. It has been reported that epigenetic modulation of the histone deacetylase (HDAC) inhibitor chidamide, as well as immune microenvironment modulation of radiotherapy are potentially synergistic with immunotherapy. Thus, the combination of chidamide, radiotherapy and immunotherapy is expected to improve prognosis of patients with advanced HER2-negative breast cancer. Patients and Methods: This is a single-arm, open, prospective clinical trial investigating the efficacy and safety of the combination of HDAC inhibitor chidamide, anti-PD-1 antibody sintilimab, and the novel immuno-radiotherapy, which aims to enhance efficacy of immunotherapy, in subsequent lines of therapy of HER2-negative breast cancer. Our study will include 35 patients with advanced breast cancer that has failed endocrine therapy and first-line chemotherapy. Participants will receive 30 mg of chidamide twice a week, 200 mg of sintilimab once every 3 weeks, combined with immuno-radiotherapy. Radiotherapy will be centrally 8 Gy for at least one lesion, and at least 1 Gy for the other lesions. We will complete three fractions of radiotherapy in one cycle. The primary endpoint is progression-free survival, and secondary endpoints are objective response rate, disease control rate and safety. Moreover, biomarkers including cytokines and lymphocyte subgroups will be explored. Conclusion: As a single-arm clinical trial, the analysis of the influence of each single treatment is limited. Besides, our study is an open study, which involves neither randomization nor blinding. In spite of the abovementioned limitations, this prospective clinical trial will give an insight into subsequent lines of therapy of HER2-negative advanced breast cancer, prolong the survival or achieve long remission for these participants, and identify potential responders.
RESUMO
Immune checkpoint inhibitors (ICIs) demonstrate unique advantages in the treatment of lung cancer and are widely used in the era of immunotherapy. However, ICIs can cause adverse reactions. Hematological toxicities induced by immunotherapy are relatively rare. Agranulocytosis, a rare hematologic adverse event associated with immune checkpoint inhibitors, has received limited attention in terms of treatment and patient demographics. Herein, we report the case of a 68-year-old male with non-small cell lung cancer(NSCLC) who received two cycles of programmed cell death-1 (PD-1) antibody sintilimab immunotherapy combined with albumin-bound paclitaxel and carboplatin chemotherapy and one cycle of sintilimab monotherapy. He was diagnosed with grade 4 neutropenia and sepsis (with symptoms of fever and chills) after the first two cycles of treatment. Teicoplanin was promptly initiated as antimicrobial therapy. The patient presented with sudden high fever and developed agranulocytosis on the day of the third cycle of treatment initiation, characterized by an absolute neutrophil count of 0.0×109/L. The patient was treated with granulocyte colony-stimulating factor but did not show improvement. He was then treated with corticosteroids, and absolute neutrophil counts gradually returned to normal levels. To the best of our knowledge, this is the first reported case of sintilimab-induced agranulocytosis in a patient with NSCLC. Sintilimab-induced severe neutropenia or agranulocytosis is a rare side effect that should be distinguished from chemotherapy-induced neutropenia and treated promptly with appropriate therapies; otherwise, the condition may worsen.
RESUMO
Background: Immune checkpoint inhibitors (ICIs) no longer are approved for second-line or later treatment of extensive-stage small cell lung cancer (ES-SCLC), and have not been studied in combination with chemotherapy. Exploring the efficacy and safety of second-line or later immunotherapy for ES-SCLC is an urgent clinical question that needs to be addressed, and combination therapies are an important research direction. This study intended to investigate the efficacy and safety of the sintilimab in combination with chemotherapy as a second-line and beyond treatment option for ES-SCLC. Methods: Medical records of patients who received treatment with sintilimab in combination with chemotherapy or chemotherapy alone as a second-line or beyond therapy were retrospectively analyzed. The study evaluated efficacy and safety. Indicators of efficacy included objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS). Safety indicators included adverse events (AEs). Results: This cohort comprised of 46 patients: 24 in the sintilimab combination chemotherapy group and 22 in the chemotherapy group. Chemotherapy received by both groups was either albumin-bound paclitaxel or irinotecan. Compared with the chemotherapy group, the sintilimab combination chemotherapy group had higher ORR and DCR (ORR: 37.5% vs. 9.1%, P=0.04; DCR: 75.0% vs. 40.9%, P=0.04), and significantly prolonged PFS and OS [median PFS (mPFS): 5.07 vs. 2.45 months, P=0.006; median OS (mOS): 14.43 vs. 10.34 months, P=0.009]. Also, there was no significant increase in the incidence of AEs in the sintilimab combination chemotherapy group, which was well tolerated by patients. Conclusions: Sintilimab in combination with chemotherapy is superior to single-agent chemotherapeutic treatment as second-line or later therapy in ES-SCLC patients who have not received prior immunotherapy. These results need to be confirmed in future clinical trials.
RESUMO
BACKGROUND: In recent years, immune checkpoint inhibitors (ICIs) have demonstrated remarkable efficacy across diverse malignancies. Notably, in patients with advanced gastric cancer, the use of programmed death 1 (PD-1) blockade has significantly prolonged overall survival, marking a pivotal advancement comparable to the impact of Herceptin over the past two decades. While the therapeutic benefits of ICIs are evident, the increasing use of immunotherapy has led to an increase in immune-related adverse events. CASE SUMMARY: This article presents the case of a patient with advanced gastric cancer and chronic plaque psoriasis. Following sintilimab therapy, the patient developed severe rashes accompanied by cytokine release syndrome (CRS). Fortunately, effective management was achieved through the administration of glucocorticoid, tocilizumab, and acitretin, which resulted in favorable outcomes. CONCLUSION: Glucocorticoid and tocilizumab therapy was effective in managing CRS after PD-1 blockade therapy for gastric cancer in a patient with chronic plaque psoriasis.
RESUMO
Purpose: We aimed to evaluate the effects of sintilimab plus radiotherapy on levels of Spondin-2 and glucose transporter-1 (Glut-1) in patients with cervical cancer. Patients and Methods: A total of 112 patients with cervical cancer treated from January 2019 to January 2021 were selected in this randomized control trial and divided into a control group (n = 56) and a study group (n = 56) using the random number table method. Chemotherapy using docetaxel + cisplatin was performed for both groups, based on which the control group was given radiotherapy (external conformal radiotherapy + intracavitary irradiation), and the study group received sintilimab plus radiotherapy. The treatment lasted for six cycles, with 21 days as one cycle. Results: The total response rate of the study group was higher than that of the control group (55.36% vs 33.93%) (P < 0.05). There were no significant differences in adverse effects between the two groups (P > 0.05). After six cycles of treatment, the levels of carcinoembryonic antigen, squamous cell carcinoma antigen, vascular endothelial growth factor-A, vascular endothelial growth factor receptor 2, Spondin-2 and Glut-1 decreased in both groups compared with those before treatment, and they were lower in the study group (P < 0.05). The survival rate of the study group was higher than that of the control group (87.50% vs 71.43%) (P < 0.05). Conclusion: Sintilimab plus radiotherapy can effectively reduce the levels of serum tumor markers, such as Spondin-2 and Glut-1, and enhance the clinical efficacy on patients with cervical cancer, without increasing adverse effects.
RESUMO
Background: Sintilimab plus chemotherapy has proven effective as a combination immunotherapy for patients with advanced gastric and gastroesophageal junction adenocarcinoma (GC/GEJC). A multi-center study conducted in China revealed a median progression-free survival (PFS) of 7.1 months. However, the prediction of response duration to this immunotherapy has not been thoroughly investigated. Additionally, the potential of baseline laboratory features in predicting PFS remains largely unexplored. Therefore, we developed an interpretable machine learning (ML) framework, iPFS-SC, aimed at predicting PFS using baseline (pre-treatment) laboratory features and providing interpretations of the predictions. Materials and methods: A cohort of 146 patients with advanced GC/GEJC, along with their baseline laboratory features, was included in the iPFS-SC framework. Through a forward feature selection process, predictive baseline features were identified, and four ML algorithms were developed to categorize PFS duration based on a threshold of 7.1 months. Furthermore, we employed explainable artificial intelligence (XAI) methodologies to elucidate the relationship between features and model predictions. Results: The findings demonstrated that LightGBM achieved an accuracy of 0.70 in predicting PFS for advanced GC/GEJC patients. Furthermore, an F1-score of 0.77 was attained for identifying patients with PFS durations shorter than 7.1 months. Through the feature selection process, we identified 11 predictive features. Additionally, our framework facilitated the discovery of relationships between laboratory features and PFS. Conclusion: A ML-based framework was developed to predict Sintilimab plus chemotherapy response duration with high accuracy. The suggested predictive features are easily accessible through routine laboratory tests. Furthermore, XAI techniques offer comprehensive explanations, both at the global and individual level, regarding PFS predictions. This framework enables patients to better understand their treatment plans, while clinicians can customize therapeutic approaches based on the explanations provided by the model.

Background: Programmed cell death-1 (PD-1) inhibitors and anti-angiogenic drugs have become a hotspot in research of anti-tumor programs; however, they can also cause some rare drug-related adverse reactions. Immune checkpoint inhibitors (ICIs) cause adverse reactions in the body, collectively known as immune-related adverse events (irAEs). Ocular side effects can occur in both targeted and immunotherapy patients, including dry eye, blurred vision, uveitis, conjunctivitis, retinopathy, or thyroid eye disease. To our knowledge, this is the first case report describing corneal ulcers secondary to dry eye in a patient treated with the combination of PD-1 inhibitor sintilimab and multi-targeted receptor tyrosine kinase inhibitor (TKI) anlotinib. Case Description: A 65-year-old woman with non-small cell lung cancer (NSCLC) and bone metastases, without pre-existing ocular conditions, experienced mild dry eye symptoms 1 month following treatment with sintilimab (200 mg q3w) in combination with anlotinib (12 mg q3w). Unrelieved dry eye symptoms occurred after the third cycle of chemotherapy, and she was diagnosed with dry eye syndrome. Subsequently, she received corneal protective lens, sodium hyaluronate eye drops, and prednisone treatment. Her corneal epithelial damage did not improve significantly, and within the following 2 months, her vision decreased in both eyes and progressed to bilateral corneal ulcers. Oral administration of sintilimab and anlotinib was interrupted, and treatments such as corticosteroids, anti-inflammatory drugs, and corneal repair were administered; however, both eyes presented with corneal subepithelial defect and corneal scarring. Due to a shortage of donors, no corneal transplantation surgery could be performed. Conclusions: The development of corneal epithelial disorders in patients receiving target therapy and immunotherapy may not be reversed by reducing its dose. Although the condition is controlled with the use of glucocorticoids, some eye side effects cannot be cured. The timely detection and intervention of adverse effects of anti-tumor drugs by oncologists and ophthalmologists is critical for rational prescription. Ophthalmologists should be aware of eye side effects in patients using immunotherapy to ensure appropriate treatment and minimize potential eye complications such as dry eye, conjunctivitis, etc.
RESUMO
Background: The most effective method and length of time for administering adjuvant immunotherapy after surgery for non-small cell lung cancer (NSCLC) are still unknown. Various clinical trials have utilized diverse strategies for adjuvant treatment. In this case, we explore the potential benefits of neoadjuvant immunotherapy combined with chemotherapy in managing locally advanced lung squamous carcinoma, which often poses challenges for treatment. This multimodal approach aims to downstage tumors and optimize surgical outcomes. Case Description: Following a diagnosis of stage IIIB lung cancer, the patient underwent three cycles of neoadjuvant therapy using sintilimab, Abraxane, and Lobaplatin, resulting in a significant 45% reduction in tumor size. Subsequently, a right lower lobe lobectomy and systematic lymphadenectomy were performed using a uniportal video-assisted thoracic surgery (VATS) approach. Postoperative analysis revealed negative lymph nodes, with only a 5-mm residual tumor in the tumor bed, downstaging the cancer to IA1. Remarkably, the patient experienced a smooth recovery without any postoperative complications. One cycle of adjuvant therapy was administered following the operation to further support the patient's recovery and minimize the risk of disease recurrence. This comprehensive treatment approach underscores the importance of neoadjuvant therapy in optimizing surgical outcomes and improving long-term prognosis for patients with locally advanced lung cancer. Conclusions: For patients with stage III locally advanced lung squamous carcinoma, the combination of Sintilimab and Platinum-based drugs can be used as a neoadjuvant therapy which can reduce the difficulty of the operation.
RESUMO
Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous disease with varying characteristics, in terms of genomic variation, cell morphology and clinical presentation. At present, only ~66% of patients are cured with initial treatment and those with refractory DLBCL exhibit a poor prognosis. Thus, further investigations into novel effective treatment options for DLBCL are required. The present study reports the case of a patient resistant to multiple therapies, including rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) plus enzastaurin (trial no. CTR20171560), GemOx plus lenalidomide and selinexor (trial no. ATG-010-DLBCL-001). The patient harbored a CD274 amplification, as identified via next-generation sequencing (NGS), and exhibited a high programmed death-ligand 1 Tumor Proportion Score of up to 95%. Consequently, the patient was treated with sintilimab monotherapy and the response lasted for 12 months of follow-up without major immune-related adverse events. This case highlights the role of NGS technology in selecting treatment options for refractory DLBCL. Furthermore, the results of the present study suggest that sintilimab may have potential in the treatment of patients with refractory DLBCL.
RESUMO
BACKGROUND: Hepatocellular carcinoma (HCC), a major contributor to cancer-related deaths, is particularly prevalent in Asia, largely due to hepatitis B virus infection. Its prognosis is generally poor. This case report contributes to the medical literature by detailing a unique approach in treating a large HCC through multidisciplinary collaboration, particularly in patients with massive HCC complicated by ruptured bleeding, a scenario not extensively documented previously. CASE SUMMARY: The patient presented with large HCC complicated by intratumoral bleeding. Treatment involved a multidisciplinary approach, providing individualized care. The strategy included drug-eluting bead transarterial chemoembolization, sorafenib-targeted therapy, laparoscopic partial hepatectomy, and standardized sintilimab monoclonal antibody therapy. Six months after treatment, the patient achieved complete radiological remission, with significant symptom relief. Imaging studies showed no lesions or recurrence, and clinical assessments confirmed complete remission. This report is notable as possibly the first documented case of successfully treating such complex HCC conditions through integrated multidisciplinary efforts, offering new insights and a reference for future similar cases. CONCLUSION: This study demonstrated effective multidisciplinary treatment for massive HCC with intratumoral bleeding, providing insights for future similar cases.
RESUMO
Background: In contemporary times, malignancies characterized by metastatic growth have been subjected to innovative therapeutic approaches involving immunological agents known as Programmed Death Receptor 1 (PD-1) inhibitors. Notwithstanding their remarkable immunotherapeutic effectiveness, these treatments can give rise to undesirable immune-related effects. Sintilimab, a PD-1 inhibitor sanctioned for marketing by the Chinese National Medical Products Administration in 2018, has been associated with 51 reported cases of adverse reactions on the market, excluding psoriasis, up to the present moment. Case Description: Herein, we report the clinical characteristics of a patient with metastatic gastric adenocarcinoma who developed guttate psoriasis after receiving Sintilimab. The patient was an elderly male presenting with papules varying in size from that of rice grains to soybeans, accompanied by scattered erythematous lesions across his body. Notably, an atypical Auspitz's sign was observed, wherein certain lesions were covered with a minimal amount of scale, coupled with reported persistent itching. The progression of the disease manifested within a span of one week. Conclusion: PD1 inhibitors have been associated with the recurrence, exacerbation, or new onset of psoriasis. Consequently, a personal or family history of psoriasis is an essential risk factor that needs to be considered before PD1 inhibitor medication, which helps with the early diagnosis of psoriasis. Early diagnosis of new-onset guttate psoriasis poses challenges. An early consultation with a dermatologist is recommended, and a conclusive diagnosis can be obtained through a histopathologic examination.
