RESUMO

Gallbladder cancer (GBC) is a rare and highly aggressive malignancy, often characterized by nonspecific clinical presentations and late diagnosis, which contribute to its poor prognosis. It is commonly detected at advanced stages, leading to low survival rates. Surgical resection is the primary treatment, with the extent of surgery depending on the T stage of the cancer. In advanced cases, surgery is only considered if it can potentially be curative. Despite various treatment approaches for advanced GBC, survival outcomes remain poor. In our case series, we introduce a novel treatment approach combining cytoreductive surgery, intraoperative radiation therapy, and hyperthermic intraperitoneal chemotherapy. Remarkably, we observed a 100% one-year survival rate, with one patient achieving eight years of disease-free survival without recurrence or metastasis. This aggressive treatment strategy did not lead to increased morbidity or mortality, suggesting its safety and feasibility. However, larger-scale studies are required to draw definitive conclusions.

RESUMO

INTRODUCTION: Pheochromocytomas are rare catecholamine-secreting tumors with a high potential for recurrence post-surgery, necessitating prolonged follow-up. This case highlights the diagnostic and therapeutic challenges in managing recurrent pheochromocytoma. CASE PRESENTATION: A 25-year-old female, with a history of left pheochromocytoma treated with adrenalectomy a decade earlier, presented with a right adrenal mass. Despite controlled hypertension, elevated urine metanephrines suggested recurrence. Imaging showed a right adrenal mass and suspicious left paraaortic lymph nodes, confirming the diagnosis of recurrent malignant pheochromocytoma in the left adrenal bed and right adrenal gland, with metastasis to the paraaortic lymph nodes. The patient underwent right adrenalectomy coupled with cytoreductive surgery (CRS) in the form of excision of left-sided adrenal bed recurrence and left paraaortic lymph node dissection, intraoperative radiation therapy (IORT), and hyperthermic intraperitoneal chemotherapy (HIPEC). On follow-up six years later, the patient remains free from recurrence. DISCUSSION: This case illustrates the importance of continued surveillance in pheochromocytoma patients, even those with a low-risk profile. The recurrence in this case, despite a smaller initial tumor size and no genetic predispositions, underscores the unpredictable nature of pheochromocytomas. The successful management with CRS, IORT, and HIPEC emphasizes the need for a personalized and multifaceted treatment approach. CONCLUSION: Pheochromocytoma patients, including those initially considered low risk, require long-term monitoring due to the risk of recurrence. The utilization of CRS, IORT, and HIPEC in this case was pivotal in managing the recurrent and metastatic malignant disease effectively, demonstrating the significance of a comprehensive, multidisciplinary treatment strategy in such complex cases.

RESUMO

Ancient schwannomas are a rare variation of schwannomas, with the distinction being based on histopathological examination of the excised specimen. On histopathological examination, ancient schwannomas exhibit degenerative changes such as calcification, hyalinization, and cystic necrosis, along with S100 positivity. Complete surgical excision is the mainstay treatment for ancient schwannomas and carries a favorable prognosis. Recurrence is the most common complication, often arising from incomplete surgical excision. Herein, we present a case of a 41-year-old male who presented to our center as a case of a retroperitoneal mass for further investigations and diagnostic workup. Imaging showed a retroperitoneal mass in the right iliac fossa. We proceeded with ultrasound guided needle biopsy, and examination of the specimen confirmed the diagnosis of ancient schwannoma. Subsequently, the patient underwent surgery, and complete surgical excision was achieved. On follow-up 3-months later, the patient is doing well, and no signs of recurrence were found.

RESUMO

BACKGROUND: Peritoneal sarcomatosis (PS) is a rare tumor with limited therapeutic options. Bidirectional intraoperative chemotherapy (BDIC) using intravenous ifosfamide and doxorubicin-based hyperthermic intraperitoneal chemotherapy (HIPEC) after cytoreductive surgery (CRS) is an emerging treatment for peritoneal malignancies. PATIENTS AND METHODS: Patients with PS who underwent CRS/BDIC using intravenous ifosfamide and HIPEC from January 2017 to July 2021 were retrospectively analyzed. The last follow-up date was May 2022. RESULTS: A total of 29 patients were included. Overall survival (OS) rates at 6, 12, 24, and 48 months after CRS/BDIC were 93.1%, 89.2%, 81.4%, and 73.3%, respectively. As of May 2022, 6 patients (20.6%) had died, including four (13.8%) with a proven recurrent tumor and two with incomplete tumor resection [completeness of cytoreduction (CC)-2 or CC-3]. Of the 20 patients (68.9%) with CC-0 or CC-1, 7 had locoregional tumor recurrence without distant metastasis, whereas the other 13 were alive with no evidence of recurrent tumor in May 2022. Disease recurrence rates were 15% at 6 months and 35% at 12, 24, and 48 months after CRS/BDIC. Clavien-Dindo class ≥ IIIa complications developed in 9 patients (31.0%) with no deaths. Leukopenia occurred in 5 patients (17.2%) and thrombocytopenia in 12 patients (41.3%); these hematologic abnormalities resolved. A total of 9 (31.0%) patients developed nephrotoxicity; all recovered except one, who progressed to chronic kidney disease. CONCLUSIONS: CRS/BDIC using intravenous ifosfamide and doxorubicin-based HIPEC is a potentially effective treatment for PS and has an acceptable rate of complications.

RESUMO

BACKGROUND Malignant mesotheliomas are rare, yet highly malignant tumors. Mesotheliomas are tumors that develop from mesothelial surfaces, with the pleura being the most common, followed by the peritoneum. The diagnosis of malignant peritoneal mesothelioma (MPM) is usually established when the disease is advanced, owing to the nonspecific clinical appearance and abdominal symptoms. Initially, MPM was treated with palliative systemic chemotherapy, with or without palliative surgery. However, cytoreductive surgery (CRS) combined with bidirectional intraoperative chemotherapy (BDIC) has recently emerged as a treatment option for MPM. BDIC creates a bidirectional chemotherapy gradient in the peritoneal tumor cells through the simultaneous use of intraperitoneal and intravenous chemotherapy. CRS, combined with BDIC (CRS-BDIC), allows the complete elimination of residual tiny tumor cells after complete removal of the visible tumor nodules. CASE REPORT Herein, we present a case of a 51-year-old woman with MPM and chronic kidney disease (CKD) stage 3b. Her treatment consisted of neoadjuvant chemotherapy and immunotherapy, followed by CRS-BDIC using intraperitoneal cisplatin and doxorubicin, and intravenous ifosfamide. The surgery was successful, with no immediate complications or decline in the patient's kidney function. On follow up 2 months later, the patient denies suffering any chemotherapy-related adverse effects, and her kidney profile remains stable. CONCLUSIONS In conclusion, nephrotoxicity, a known adverse effect of cisplatin and ifosfamide, might not be a contraindication for the use of these potentially nephrotoxic drugs in CRS-BDIC in patients with renal impairment.

RESUMO

Guillain-Barré syndrome (GBS) is a rare immune-mediated neuropathy causing destruction of the peripheral nervous system, with molecular mimicry playing a major role in its pathophysiology. Despite its rarity, it is considered the most common cause of acute flaccid neuromuscular paralysis in the United States. Although diagnosing GBS depends on the clinical presentation of the patient, cerebrospinal fluid sampling, nerve conduction studies, electromyography, magnetic resonance imaging, and ganglioside antibody screening can be used to confirm the diagnosis and rule out other differentials. Here, we report a rare case of GBS as a postoperative complication after a successful gastrojejunostomy to excise an adenocarcinoma in the second part of the duodenum. Such a complication is rare and not fully understood yet.

RESUMO

Rosai-Dorfman Disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy, is an uncommon histiocytic condition characterized by massive histopathological aggregation of CD1-a negative, CD68-positive, and S100-positive histiocytes. It was initially described by Destombes in 1965 under the term "adenitis with lipid excess." However, it is named after Rosai and Dorfman who reported further histopathological features of the disease in 1969. The diagnosis of this non-Langerhans cell histiocytosis can be challenging and requires high clinical suspicion. The diagnostic process usually involves imaging, tissue biopsies, and genetic testing as needed. In this case series, we are presenting three cases of rare disease. Case 2 had both nodal and extranodal forms, which makes this case rarer than cases 1 and 3, which present with extranodal lesions.

RESUMO

BACKGROUND Malignant peritoneal mesothelioma (MPM) is an aggressive neoplasm with a poor prognosis. Bidirectional intraoperative chemotherapy (BDIC) using concurrent intraperitoneal and intravenous chemotherapy in combination with cytoreductive surgery (CRS) is an emerging treatment option for selected cases of MPM. It is a locoregional treatment that involves intraoperative chemoperfusion of heated chemotherapy. The administration of systemic along with intraperitoneal chemotherapy allows for a bidirectional chemotherapy gradient in peritoneal tumor cells. The aim of this treatment is eradication of microscopic residual cancer cells after major removal of macroscopic tumor nodules. To date, there is no consensus on the chemotherapeutic regimen that can be used in BDIC to manage MPM in patients with severe renal impairment. Administering intravenous ifosfamide with hyperthermic intraperitoneal cisplatin and doxorubicin is a promising regimen in treating peritoneal mesothelioma. Nephrotoxicity is a dose-limiting adverse effect of cisplatin and ifosfamide. Therefore, dose adjustment is required in patients with renal impairment. CASE REPORT In this report, we describe a 46-year-old female patient with recurrent MPM and severe renal impairment. Her treatment was managed with hyperthermic intraperitoneal cisplatin and doxorubicin along with intravenous ifosfamide following CRS. The cisplatin dose was reduced to 50% and the ifosfamide dose was reduced by 25%. The patient tolerated the procedure well, without deterioration in her renal function. At her 9-month follow-up, she did not report experiencing chemotherapy-related adverse effects, and her kidney function remained stable. CONCLUSIONS Severe renal impairment might not be a contraindication to using potentially nephrotoxic chemotherapeutic agents in CRS-BDIC.

RESUMO

BACKGROUND: Intraoperative radiation therapy (IORT) is a highly conformal type of radiation therapy given at time of surgery aiming for better tumor local control. It increases the tumor radiation dose without exceeding normal tissues tolerance doses. PURPOSE: To assess the feasibility of IORT and short-term toxicities in patients with different cancer sites treated with multidisciplinary protocol including IORT. PATIENTS AND METHODS: Medical records of cancer patients who received IORT as a part of their multidisciplinary treatment at King Faisal Specialized Hospital and Research center (KFSH&RC), Riyadh, Saudi Arabia, from January 2013 until December 2017 were retrospectively reviewed. RESULTS: A total of 188 patients with 210 IORT applications were analyzed. Twenty-two patients had two applications at the same time. One hundred sixteen patients were males. Median age at time of diagnosis was 49.5 years (19-77). One hundred thirty-four patients had primary, while 54 cases had recurrent disease. Gastroesophageal cancer and soft tissue sarcoma were the most frequent diagnosis in 49 patients followed by colorectal cancer in 35 patients. Major surgeries with curative intent done in 183 patients (97.3%). Hyperthermic intraperitoneal chemotherapy (HIPEC) was performed in 118 (62.8%) patients. The 30-day postoperative mortality rate was 3.2%. Fifty-four (28.7%) patients develop grades III-IV complications according to Clavien-Dindo grading system. CONCLUSION: The data presented discusses using of IORT treatment for different malignant tumors as a part of multimodality treatment. IORT seems safe and feasible; however, a longer follow-up period is needed for proper evaluation and to define the role of IORT in a tailored multimodality approach.

RESUMO

Adamantinoma, constituting a minute fraction of primary bone tumors, poses a diagnostic challenge due to its ambiguous histogenesis. This report outlines a distinctive case involving a 27-year-old female with a history of right tibial adamantinoma, presenting with bilateral pulmonary emboli and metastasis to the ovaries and pelvic lymph nodes. Following en bloc resection five years earlier, the patient underwent debulking surgery with hyperthermic intraperitoneal chemotherapy (HIPIC) and intraoperative radiotherapy (IORT) as a palliative measure. The procedure achieved substantial pelvic tumor reduction, and subsequent follow-ups indicated a favorable postoperative trajectory. This case underscores the rarity of adamantinoma metastasis to the ovaries and pelvis, being the first reported instance, shedding light on the challenges and potential benefits of a multimodal palliative approach. Further research is warranted to refine treatment strategies for metastatic adamantinoma and enhance patient outcomes.

RESUMO

Patients with an oncologic disease requiring cytoreductive surgery and hyperthermic intraperitoneal chemotherapy may also present with morbid obesity. In some patients, it may be possible to offer bariatric surgery such as sleeve gastrectomy in combination with their cancer resection to treat both diseases concurrently. Two such cases are described where sleeve gastrectomy was done alongside the primary oncologic surgery in the same procedure. Our patients had long-term follow-ups and their overall outcomes were favorable. They achieved remission and acceptable levels of weight loss over their several years of follow-up appointments. The added benefit of bariatric surgery may decrease long-term morbidity and mortality in carefully selected patients. More studies are indicated to fully understand the risks of benefits of this combined procedure in order to offer it on a wider scale.

RESUMO

Lemmel syndrome is a rare cholestatic disease caused by a periampullary duodenal diverticulum (PAD) compressing the common bile duct (CBD) or pancreatic duct, which results in acute abdominal pain and/or obstructive jaundice in the absence of other pathology explaining the symptoms. It can be easily misdiagnosed unless carefully detected by abdominal ultrasound (US), barium studies, computed tomography (CT) scan, esophagogastroduodenoscopy (EGD), magnetic resonance cholangiopancreatography (MRCP), and endoscopic retrograde cholangiography (ERCP), which is also the treatment modality of choice. We herein report a case of a 62-year-old male presenting with prolonged hypochondrial pain. He was diagnosed with Lemmel syndrome after performing US, barium meal, CT scan, EGD, and MRCP that was managed successfully by ERCP with sphincterotomy and stent placement.

RESUMO

Although the incidence of gastric cancer has decreased worldwide, it is still among the most common cancers worldwide. Usual manifestations of gastric cancer include gastrointestinal-related symptoms such as weight loss and abdominal pain. Isolated symptomatic bony metastasis at initial presentation is very rare. Here, we present an infrequent case of a middle-aged lady who presented with a left femur neck fracture and left eye esotropia as the initial presenting clinical manifestations of gastric cancer. She was found to have an isolated bone metastasis seen throughout the body skeleton with no extraosseous metastasis. The patient was treated conservatively and received external beam radiation therapy as part of palliative therapy. This report signifies the importance of considering the diagnosis of gastric cancer in middle-aged patients with isolated symptomatic bone metastasis. It also reviews the overall poor prognosis of such cases and recommends further studies on the role of chemotherapy and radiation therapy in such cases.

RESUMO

Appendiceal mucinous adenocarcinoma is a term that was given for invasive appendiceal tumors. It is always present with pseudomyxoma peritonei which is a complex disease. These tumors have the tendency to surround the primary tumor then extend primarily and extensively all over the peritoneal cavity as the primary site of metastases. The invasion through the abdominal wall muscles is rare but the penetration and passing through these muscles to the subcutaneous tissue are extremely rare. A 62-year-old male patient known to have pseudomyxoma peritonei presented with gluteal abscess. After 2 weeks from the abscess drainage, the patient underwent cytoreductive surgery (CRS) combined with intraoperative radiotherapy (IORT) and hyperthermic intraperitoneal chemotherapy (HIPEC). He tolerated the operation well and discharged home in a good condition. Even with extensive appendiceal mucinous neoplasms presented with the penetration of the abdominal wall muscles, still aggressive management should be considered.

RESUMO

BACKGROUND: Pancreatic cancer is leading cause of cancer related deaths. The prognosis is usually very poor. In spite of the advances in modern surgery, the outcome is still poor. IORT was recently introduced with recorded improvement in both locoregional tumor control and patient survival. Prophylactic HIPEC was introduced during the initial surgery in order to prevent subsequent peritoneal cancer or tumor recurrence which showed some encouraging results. AIM OF WORK: Evaluation of the perioperative results of the combination of IORT and HIPEC with CRS as a novel approach in the management of resectable pancreatic cancer. PATIENTS AND METHODS: This study was conducted at King Faisal Specialist Hospital and Research Center, Riyadh, Kingdom of Saudi Arabia. Data were collected retrospectively. A total of five patients were included in the study, during the period from November 2017 to August 2018. All surgeries were done by the same surgeon. RESULTS: The average age was 51 years (25-63). The patients were two males and three females. All the patients underwent complete surgical resection combined with IORT then HIPEC. All patients were discharged home in good condition. They were regularly followed up without any evidence of local recurrence or metastases. CONCLUSION: The combination of IORT and HIPEC with CRS gives the addition of the benefits of each procedure alone without affecting the postoperative morbidity or mortality. This combination appeared to be feasible, safe and well tolerated. However, this need to be applied on a larger number of patients with longer periods of follow-up to reach sound conclusions.

RESUMO

BACKGROUND: Leprosy is a chronic contagious disease caused by Mycobacterium lepraea. CD163 is a monocyte trans-membrane glycoprotein receptor (mCD163) that sheds from the cell surface and circulates as a soluble (serum) form (sCD163). Changes in the mCD163 and sCD163 levels could mirror the categorization of inflammatory procedure, demonstrating a possible use of CD163 as a diagnostic indicator of inflammation. OBJECTIVE: To investigate the possible role of CD163 (sCD163 and mCD163) in leprosy pathogenesis and to assess whether CD163 is a helpful inflammatory marker of leprosy development and typing. PATIENTS AND METHODS: This case control study included 70 leprosy patients and 30 healthy controls. Leprosy patients were classified according to the Madrid criteria (1953) into: tuberculoid leprosy (TT), border-line leprosy (BL), and lepromatous leprosy (LL). For all participants, complete blood count (CBC), serum CD163 using ELISA and monocytes positive for CD163 using flow cytometry were done. RESULTS: Leprosy patients had significantly low WBCs and platelet counts (p<0.001) and had significantly higher sCD163 (p=0.025) and mCD163 (p=0.042) that were highest in LL followed by BL, then TT patients (p<0.001). There was a significant positive correlation between mCD163 and sCD163 levels in leprosy patients (r=0.896, p<0.001). ROC analysis revealed a significant role of serum sCD163 and of mCD163 positive monocytes in the detection (p<0.001) and typing of leprosy (p=0.002 and p<0.001, respectively). CONCLUSION: Both sCD163 and mCD163 positive monocytes may have an active role in leprosy pathogenesis. They could be potential biomarkers for leprosy detection and typing.

RESUMO

AIM: Published reports showed conflicting results regarding the sustained alterations in leptin, chemerin, and ghrelin concenratios after metabolic surgery. Therefore, we performed the present work to contrast the alterations in leptin, chemerin, and ghrelin levels one year after Roux-en-Y gastric bypass (RYGB) versus laparoscopic sleeve gastrectomy (LSG). METHODS: The present research is a prospective, comparative one that followed 100 cases for whom RYGB or LSG was done. We assessed the serum values of adiposity-associated mediators, including adipokcytokines (leptin and active chemerin) and gastrointestinal hormones (total ghrelin). The primary outcome in the present study was the alterations in leptin, chemerin, and ghrelin values at 12 months after RYGB and LSG. RESULTS: The serum leptin level decreased significantly in the LSG group with a mean change of - 170.8 ± 29.4 ng/mL (p < 0.001). Similarly, the serum leptin concentration decreased significantly in the RYGB group, with a mean change of - 165.42 ± 53.4 (p < 0.001). In addition, the mean reduction in baseline chemerin levels 12 months after the operation was considerable in the LSG cohort (- 23.24 ± 9.5 ng/mL) and RYGB group (- 22.12 ± 15.9 ng/mL). The ghrelin values demonstrated a notable reduction in the LSG cohort (- 0.083 ± 0.11 pg/mL) and RYGB group (- 0.068 ± 0.097 pg/mL). However, the changes in the three hormones were not substantially different between both groups (p > 0.05). CONCLUSION: Both RYGB and LSG result in a considerable, comparable decrease in the postoperative serum concentrations of leptin, chemerin, and ghrelin.

RESUMO

Hepatocellular carcinoma (HCC) is a serious consequence of persistent hepatitis C virus (HCV) infection and represents one of the most aggressive neoplasms globally. The implication of microRNA-301 (miR-301) in the initiation and progression of different types of cancers has been proved. We aimed to assess circulating microRNA-301 as possible biomarker for the early detection of HCC in patients with chronic HCV infection. miR-301 expression levels were estimated in plasma samples of 42 patients with newly diagnosed HCV-related HCC, 48 chronically HCV infected patients with liver cirrhosis and 40 healthy individuals by reverse transcription-quantitative polymerase chain reaction technique. In comparison with chronically HCV infected patients and healthy controls, miR-301 expression levels were significantly increased in HCC patients (P < 0.001). miR-301 levels distinguished HCC patients from chronic HCV patients, with area under the receiver-operating characteristic curve of 0.89 (95% CI 0.82-0.96), the sensitivity and the specificity were 78.57% and 89.58% respectively. Moreover, miR-301 levels were significantly linked with tumor size (P = 0.014), serum levels of alpha-fetoprotein (AFP) (P = 0.028) and Barcelona Clinic Liver Cancer (BCLC) score (P = 0.003). These results reveal that miR-301 can serve as a promising non-invasive biomarker for diagnosis of HCC in chronically HCV infected patients.

RESUMO

BACKGROUND: Gastric cancer can metastasize to multiple organs but the metastases to brain is very rare. We report a case of recurrent gastric cancer. The only site of recurrence is brain metastases that occurred three years after curative resection. CASE PRESENTATION: A 58-year-old male patient who was diagnosed to have gastric cancer. He received neoadjuvant chemotherapy then complete resection. The patient came to the outpatient clinic for regular follow up. After three years from resection the patient complained of headache and seizures. CT scan brain showed right temporal bone localized tumor. Complete resection was done which revealed it is a localized metastases from gastric cancer. CONCLUSION: Localized brain metastases from gastric cancer is a rare event. Urgent CT scan must be done if the patient had any neurological complaint. Early diagnosis is the key for the patient management. Rapid treatment can improve the patient general condition and neurological manifestations.

RESUMO

Nasogastric tubes (NGTs) are important for feeding, stenting and decompression after gastrointestinal surgeries, particularly in the upper gastrointestinal tract. Resistance in the removal of a NGT is a rare surgical complication and may be due to a knot in the tube or a stitch anchoring the tube to an anastomosis. We report a 41-year-old male patient who was admitted to the King Faisal Specialist Hospital & Research Center, Riyadh, Saudi Arabia, in 2015 with stomach cancer. He underwent a radical total gastrectomy with a Roux-en-Y oesophagojejunostomy. One week after the surgery, removal of the NGT was attempted; however, this was very difficult and the proximal end of the tube was cut off as a temporary measure. Six weeks later, an upper gastrointestinal tract endoscopy revealed that the distal end of the NGT had been accidentally stitched to the Roux-en-Y oesophagojejunostomy. The stitch was removed and the rest of the NGT was successfully extracted using a snare.
