Solitary late recurrence of renal cell carcinoma

Late recurrence of chromophobe renal cell carcinoma to unusual sites after 12 years of radical nephrectomy and radiotherapy: a rare case report from Syria

In 2020, renal cell carcinoma (RCC) had an incidence of 73 750 new cases. This cancer is well known for its ability to give early and late metastases to some usual and unusual sites. The term 'late recurrence' is widely used to indicate a period exceeding 10 years from curative nephrectomy. This not-understood behaviour is almost specific to RCC, and it happens in a range between 4.3 and 11% of cases of RCC.

Case Presentation

We report a case of a 67-year-old nonalcoholic smoker Syrian male presented with a 2-month painful mass located at the left upper posterolateral abdominal wall's region. He has had a history of left chromophobe cell RCC treated with radical nephrectomy with adjuvant radiotherapy for 12 years. In light of computed tomography's findings, a surgical biopsy was performed, and a pathological and immunohistochemical examination confirmed the diagnosis of chromophobe RCC.

Clinical Discussion

Malignant cells seeding the surgical cut path and staying dormant for 12 years is the best theory of many to explain our case.

Conclusion

We reported evidence for the potential of a relatively indolent histologic type of RCC (i.e. chromophobe cell carcinoma) to cause late recurrence after 12 years to a very rare site (i.e. abdominal wall's superficial muscles). Research should focus on addressing late recurrence to determine the best surveillance protocols; investigating malignant cells seeding during surgery to improve surgical oncology's outcomes; and studying late recurrence's genetics to boost our targeted therapy options.

Metastatic pulmonary nodule after a seventeen-year disease-free interval resected through thoracoscopic subsegmentectomy: A case report

The lung is the most common site of metastasis in patients with renal cell carcinoma (RCC). Metastatic RCCs, even those classified as stage I, can recur after >10 years. Therefore, it is critical to completely resect metastatic nodules. Here, we report the case of a 74‐year‐old man who underwent a nephrectomy for RCC and was diagnosed with lung metastasis 17 years later. The metastatic nodule was resected through complete thoracoscopic subsegmentectomy. He had previously undergone partial nephrectomy for clear cell renal carcinoma pT1bN0M0. During his annual follow‐up, a computed tomography scan revealed a pulmonary nodule. The intraoperative frozen section revealed a metastatic clear cell RCC. Thus, additional lobectomy was not performed. The postoperative course was uneventful with no complications. This case demonstrates that even early stage metastatic clear cell renal carcinoma can recur after over 17 years. Thoracoscopic segmentectomy is less invasive and can preserve pulmonary function.

Solitary, Late Metastatic Recurrence of Renal Cell Carcinoma to the Pancreas: A Case Report

Renal cell carcinoma (RCC) accounts for 3% of all adult malignancies and is known for metastatic initial presentation, unpredictable metastatic pathway, and late recurrence post-curative resection. We report a case of solitary late metastatic renal cell carcinoma to the pancreas more than 10 years after radical nephrectomy. A high index of suspicion must be maintained to detect RCC late recurrence and metastasis to rare and atypical locations. A lifelong follow-up is recommended.

Skeletal Muscle Metastases from Renal Cell Carcinoma: A Case Report

In this paper, we describe a case of a 73-year old female with late skeletal muscle metastases from a clear-type renal cell carcinoma 8 years after total nephrectomy. The metastases were located in the right femoral quadriceps, in the sartorius muscle and adductor magnus muscle. A full clinical work-up was performed with blood examinations, radiological and pathological assessment. A complete surgical resection with a wide margin was performed for all lesions, and the final pathological report deposed for metastatic renal carcinoma clear-type cells. In this case report, we discuss the crucial rule of accurate radiological and pathological assessment and aggressive surgical management.

Renal cell carcinoma : clinical features and management

In 1999 it was estimated that renal cell carcinoma (RCC) would account for 29,990 new cancer cases diagnosed in the United States (61% in men and 39% in women), and lead to 11,600 deaths. RCC accounts for 2-3% of all malignancies in adults and causes 2.3% of all cancer deaths in the United States annually (1). Approx 4% of all RCC cases are bilateral at some point in the life of the patient. Data from over 10,000 cases of renal cancer entered in the Connecticut Tumor Registry suggests an increase in the incidence of renal cancer from 1935-1989; in women the incidence increased from 0.7 to 4.2 in 100,000, and in men from 1.6 to 9.6 in 100,000 (2). Factors implicated in the development of RCC include cigarette smoking, exposure to petroleum products, obesity, diuretic use, cadmium exposure, and ionizing radiation (3-9).

Unusual upper gastrointestinal bleeding due to late metastasis from renal cell carcinoma: a case report

A case of recurrent massive upper gastrointestinal bleeding originating from metastatic renal cell carcinoma is reported. A 63-year-old woman underwent right nephrectomy 9 years previously and experienced no recurrence during follow-up. A gradually enlarging ulcerative tumor over the bulb of the duodenum and four subsequent episodes of massive bleeding from this tumor occurred between June 2001 and March 2002. The patient underwent surgery in April 2002 for intractable bleeding from the tumor. Renal cell carcinoma metastasis to the duodenum was confirmed from the surgical specimen. Upper gastrointestinal bleeding due to malignancy is very rare and the duodenum is the least frequently involved site. Furthermore, a solitary late renal cell carcinoma metastasis 9 years after a nephrectomy is extremely uncommon. This case suggests that life-long follow-up of renal cell carcinoma patients is necessary, owing to unpredictable behavior and the possibility of long disease-free intervals. In nephrectomized patients suffering from gastrointestinal bleeding, complete evaluation, especially endoscopic examination, is indicated. The possibility of late recurrent renal cell carcinoma metastasis to the gastrointestinal tract should be kept in mind, although it is rare. If the patient is fit for surgery, metastatectomy is the first choice of treatment.

Multiple intramuscular metastases 15 years after radical nephrectomy in a patient with stage IV renal cell carcinoma

We report an 81-year-old man with late recurrent multiple metastases in skeletal muscles 15 years after radical nephrectomy was carried out for stage IV renal cell carcinoma (RCC). The tumors were located in the left triceps muscle and the brachioradial muscle. We performed surgical resections of both tumors, and histological analysis revealed that they were both metastatic RCC of the clear-cell type. In this case report, we discuss the characteristics and differential diagnosis of this tumor on magnetic resonance imaging, and we also refer to the rarity of muscle metastasis and the unpredictable tendency of this tumor to remain dormant for long periods.

Prognostic significance of tumor grade for renal cell carcinoma

BACKGROUND

The natural history and prognosis of renal cell carcinoma cannot be predicted. Based on the Japanese classification system, the value of nuclear grade were assessed as a possible prognostic factor for renal cell carcinomas.

METHODS

In this retrospective study of 116 patients with renal cell carcinoma, radical nephrectomy was performed. Survival rates were calculated using the Kaplan-Meier method and multivariate analysis was performed using Cox's proportional hazard model.

RESULTS

Distribution by stage and grade in the population of renal cell carcinomas was as follows: pT1 in 13 cases (11.3%), pT2 in 65 cases (56.5%), pT3 in 36 cases (31.3%) and pT4 in one case (0.9%) and grade 1, 28 (24.1%), grade 2, 69 (59.5%) and grade 3, 16 (13.8%). Three cases could not be determined because of pre-operative embolization of the renal cell carcinomas. Nuclear grade was correlated with stage (P=0.0002), the presence of perirenal fat involvement (P=0.003) and metastases (P=0.007). A significant difference in survival was found between grades 1 and 3 (P=0.0001) and grades 2 and 3 (P=0.0001), respectively. Survival was significantly correlated with sex (P=0.0125), tumor size (P=0.0001), the presence of lymph node metastasis (P=0.0001), renal vein involvement (P=0.0001), perirenal fat involvement (P=0.002) or distant metastasis (P=0.0001). The multivariate analysis showed that the occurrence of tumor grade (P=0.0006) or distant metastasis were independent prognostic values.

CONCLUSION

The observations lead us to conclude that the nuclear grade according to the Japanese classification system appears to be of reliable prognostic value for renal cell carcinomas.

Recurrent renal cell carcinoma after 45 years

Late recurrence of renal cell carcinoma (RCC), arbitrarily defined as > 10 years post nephrectomy, is rare. The longest known clinical disease-free interval of 36 years was reported by Walter and Gellespie in 1960. We report a case of recurrent RCC presenting 45 years after nephrectomy.

Conservative surgery of renal cell tumors in 140 patients: 21 years of experience

Operative method, course and complications were analyzed retrospectively in 140 patients who underwent a conservative operation for renal tumor between June 1969 and December 1990. In 53 patients (20 women and 33 men, mean age 61.2 years, range 38 to 77 years, with 49 renal cell carcinomas and 4 benign renal tumors) there was an imperative indication for an organ preserving operation because nephrectomy would have made dialysis obligatory. In 87 patients (29 women and 58 men, mean age 53.7 years, range 27 to 74 years, with 72 renal cell carcinomas and 15 benign renal tumors) the tumor was conservatively resected in the presence of a normal contralateral unit (elective indication) and 68 of these patients (78%) were symptom-free. In the imperative group 32 of 49 patients (65.3%) with renal cell carcinoma had no evidence of disease after a mean followup of 4.6 years. Known metastases were present in 4 of 7 patients who died of the tumors in this group. In 3 patients with an imperative indication for conservative surgery a second tumor occurred in the kidney: 2 were treated with further parenchyma sparing operations, while in 1 with poor physical condition no further measures were possible. Of 72 patients with renal cell carcinoma who underwent an elective operation 68 (94.4%) had no signs of tumor progression after a mean followup of 3.3 years. One patient died of tumor metastases, and 2 (2.7%) had tumor recurrence in the kidney requiring nephrectomy and enucleation, respectively. The 5-year cause-specific survival rates for the imperative and elective groups were 84% and 96%, respectively. Patients with a local stage T3 tumor were characterized by a significantly worse survival curve than those with a stage T1 or T2 tumor but no significant difference was noted among the various grades of differentiation.

Solitary late recurrence of renal cell carcinoma presenting as duodenal ulcer

The natural history of renal cell carcinoma is often unpredictable and even bizarre. We report a case of solitary late recurrence of renal cell carcinoma presenting as a duodenal ulcer and review the relevant literature.

Metastatic renal cell carcinoma (RCC): spontaneous regression, long-term survival and late recurrence

We report 4 cases of metastatic renal cell carcinoma (RCC) with long-term survival either following radical nephrectomy alone or in combination with radio- or hormonal therapy. Two patients with lymph node metastases showed a long-term survival of 12 or more years following radical tumour nephrectomy (with lymphadenectomy) and radiotherapy. One of them exhibited a histologically proven tumour recurrence nearly 12 years after primary surgical treatment and died shortly later; the other one is still without any evidence of metastatic disease. Two other patients exhibited spontaneous regression of pulmonary metastases: one regression occurred after radical tumour nephrectomy alone, the other one after successful primary hormonal treatment and subsequent radical tumour nephrectomy. The following important aspects are emphasized: 1. Renal cell carcinoma is a very unpredictable tumour. Once the diagnosis of renal cell carcinoma is proved, a patient can never be considered cured. 2. Although adjuvant palliative nephrectomy has produced contradictory results in several reports, radical tumour nephrectomy either alone or in combination with other adjuvant therapies such as radiotherapy, hormonal or immunological treatment, can be worthwhile. Cases with long-term survival and spontaneous regression of distant metastases are proof of this. Besides, if carefully selected, the mortality rate of different adjuvant therapies is not significantly higher in patients with metastatic disease than in patients without metastases. The world literature on this subject is reviewed.

Progression and survival after renal-conserving surgery for renal cell carcinoma: experience in 104 patients and extended followup

Of 104 patients who underwent a conservative operation for renal cell carcinoma 42 underwent partial nephrectomy, 60 underwent enucleation and 2 underwent a combination of these procedures. A total of 14 patients required an extracorporeal operation with autotransplantation. Forty patients had bilateral renal cell carcinoma (20 were synchronous and 20 were asynchronous) and 39 had either a solitary kidney or a poorly functioning contralateral renal unit. An operation was performed in the presence of a normal contralateral unit in 20 patients. The maximal duration of followup was 20 years (mean 4.9 years): 43, 17 and 7 patients were followed for 5 or more, 10 or more and 15 or more years, respectively. The 5-year cause-specific survival rates were 88.6 +/- 5.6, 91.6 +/- 4.7 and 88.9 +/- 3.8%, respectively, for the enucleation group, partial nephrectomy group and all patients combined. The percentages of patients free of local recurrence at 5 years for the enucleation and partial nephrectomy groups were 94.6 +/- 3.9 and 93.3 +/- 4.7%, respectively. The 14 patients who required an ex vivo approach had larger, higher stage and higher grade tumors, and a poorer outcome (5-year cause-specific survival rate and local rate free of recurrence were 54.9 +/- 17.2 and 85.7 +/- 13.2%, respectively). None of the 20 patients with a normal contralateral unit had progression. The local survival rate free of disease and cause-specific survival rate were not significantly different for the simple enucleation and partial nephrectomy groups. Even longer followup is needed to assess more clearly the definitive role of simple enucleation in the treatment of renal cell carcinoma and the clinical relevance of possible positive margins in a patient population that usually is older.
