RESUMEN

RATIONALE: A hormone-active metastatic Hürthle cell thyroid carcinoma (HCTC) and Graves disease (GD) present a therapeutic challenge and is rarely reported. PATIENT CONCERNS: We present a 64-year-old male patient, who had dyspnea and left hip pain lasting 4 months. He had clinical signs of hyperthyroidism and a tumor measuring 9 cm in diameter of the left thyroid lobe, metastatic neck lymph node and metastases in the lungs, mediastinum, and bones. DIAGNOSIS: Laboratory findings confirmed hyperthyroidism and GD. Fine-needle aspiration biopsy and cytological investigation revealed metastases of HCTC in the skull and in the 8th right rib. A CT examination showed a thyroid tumor, metastatic neck lymph node, metastases in the lungs, mediastinum and in the 8th right rib measuring 20 × 5.6 × 4.5 cm, in the left acetabulum measuring 9 × 9 × 3 cm and parietooccipitally in the skull measuring 5 × 4 × 2 cm. Histology after total thyroidectomy and resection of the 8th right rib confirmed metastatic HCTC. INTERVENTIONS: The region of the left hip had been irradiated with concomitant doxorubicin 20 mg once weekly. When hyperthyroidism was controlled with thiamazole, a total thyroidectomy was performed. Persistent T3 hyperthyroidism, most likely caused by TSH-R-stimulated T3 production in large metastasis in the 8th right rib, was eliminated by rib resection. Thereafter, the patient was treated with 3 radioactive iodine-131 (RAI) therapies (cumulative dose of 515 mCi). Unfortunately, the tumor rapidly progressed after treatment with RAI and progressed 10 months after therapy with sorafenib. OUTCOMES: Despite treatment, the disease rapidly progressed and patient died due to distant metastases. He survived for 28 months from diagnosis. LESSONS: Simultaneous hormone-active HCTC and GD is extremely rare and prognosis is dismal. Concomitant external beam radiotherapy and doxorubicin chemotherapy, followed by RAI therapy, prevented the growth of a large metastasis in the left hip in our patient. However, a large metastasis in the 8th right rib presented an unresolved problem. Treatment with rib resection and RAI did not prevent tumor recurrence. External beam radiotherapy and sorafenib treatment failed to prevent tumor growth.

RESUMEN

Besides histologic features, the presence of nodal metastasis is the most crucial prognostic factor for recurrence and survival for patients with gynecologic cancer. Conventionally, lymphadenectomy has been performed routinely to assess lymphatic metastasis. However, lymphadenectomy may be unnecessary in early-stage gynecologic cancer, because the percentage of patients with lymph node involvement is very low. The recent use of sentinel lymph node mapping has provided high feasibility, safety, and accuracy in the assessment of nodal metastasis. The National Comprehensive Cancer Network Clinical Practice Guidelines have incorporated the sentinel lymph node for nodal evaluation in vulvar, endometrial, and cervical cancers.

RESUMEN

Background: There is a lack of large studies focusing on the prognostic significance of lateral lymph node (LLN) metastasis following LLN dissection (LLND) in rectal cancer. The aim of this study was to evaluate the prognostic impact of LLN metastases on survival of patients with advanced low rectal cancer. Methods: Consecutive patients with locally advanced, but not metastatic, extraperitoneal rectal cancer treated with neoadjuvant (chemo)radiotherapy plus total mesorectal excision between 2004 and 2015 were included in the study. LLND was performed when pretreatment imaging documented enlarged LLNs (7 mm or greater in size). Localization of nodal metastases and long-term outcomes were analysed. Kaplan-Meier analysis was used to compare the survival of patients with ypN0 disease with that of patients with mesorectal ypN+/LLN- status and patients with positive LLNs. The Cox proportional hazards model was used to evaluate predictors of disease-free survival (DFS) and local recurrence. Results: A total of 613 patients were included in the study; LLND was performed in 212 patients (34·6 per cent) and 57 (9·3 per cent) had LLN metastasis. Patients with LLN metastasis had improved DFS and local recurrence cumulative incidence rates compared with patients with mesorectal ypN2+/LLN- disease (DFS: P = 0·014; local recurrence: P = 0·006). Although the DFS rate of patients with LLN metastasis was worse than that of patients with ypN0 disease (P < 0·001), the cumulative incidence of local recurrence was similar (P = 0·491). In multivariable analysis, residual LLN metastasis was not an independent predictor of worse DFS or local recurrence. Conclusion: LLN metastasis is not an independent predictor of local recurrence or survival. Survival of patients presenting with LLN metastasis after (chemo)radiotherapy was intermediate between that of patients with ypN0 status and those with mesorectal ypN2 positivity.


Antecedentes: No existen en la literatura grandes estudios dirigidos a investigar la importancia pronóstica de las metástasis en los ganglios linfáticos laterales (lateral lymph nodes, LLN) después de la disección de los mismos (LLN dissection, LLND) en pacientes con cáncer de recto. El objetivo de este estudio fue evaluar el impacto pronóstico de las metástasis en los LLN sobre la supervivencia de los pacientes con cáncer de recto. Métodos: Se analizaron 613 pacientes consecutivos con cáncer de recto localmente avanzado extraperitoneal y no metastásico tratados con (quimio)radioterapia neoadyuvante seguida de resección total del mesorrecto (total mesorectal excision, TME) entre 2004 y 2015. Se realizó una LLND cuando el estudio mediante pruebas de imagen previo el tratamiento mostró LLN aumentados de tamaño ≥ 7 mm. Se analizó la localización de las metástasis ganglionares y los resultados a largo plazo. El análisis de supervivencia se realizó mediante el método de Kaplan­Meier para comparar las supervivencias de los pacientes ypN0 frente a los pacientes ypN con positividad mesorrectal/LLN negativos y frente a los pacientes LLN positivos. Se utilizó el modelo de riesgo proporcional de Cox para evaluar los factores predictivos de supervivencia libre de enfermedad y de recidiva local. Resultados: Se realizó una LLND en 212 (34,6%) pacientes, y 57 (9,3%) pacientes presentaban metástasis en los LLN. Los pacientes con metástasis en los LLN presentaron mejores curvas de incidencia acumulada de recidiva local y de supervivencia libre de enfermedad en comparación con los pacientes con ganglios mesorrectales ypN2 positivos/LLN negativos (respectivamente, P = 0,0135 y P = 0,0060). Aunque la curva de la supervivencia libre de enfermedad de los pacientes con metástasis en los LLN fue peor que la de los pacientes ypN0 (P < 0,0001), la incidencia acumulada de recidiva local fue similar (P = 0,4905). En el análisis multivariable, la metástasis residual en los LLN no fue un factor predictivo independiente de peor supervivencia libre de enfermedad ni de recidiva local. Conclusión: Las metástasis en los LLN no es un factor predictivo independiente de recidiva local o supervivencia. Los pacientes que presentaron metástasis en los LLN después de (quimio)radioterapia mostraron características de supervivencia intermedias entre ypN0 y pacientes con ganglios mesorrectales ypN2 positivos.

RESUMEN

We present the case of a 55-year-old male patient who presented with palpable cervical lymphadenopathy. Excisional biopsy showed metastatic adenocarcinoma of unknown origin. Imaging showed a bladder mass following which he underwent transurethral resection of bladder tumour. Histopathological evaluation of mass confirmed a poorly differentiated adenocarcinoma with signet-ring cell features. Immunohistochemistry was suggestive of metastatic urachal cancer. He agreed for enrollment in a clinical trial, however soon after 1st cycle, he developed immune pneumonitis requiring high dose steroids. On follow-up, MRI brain was done for evaluation of headache which showed metastatic intracranial disease. He completed radiotherapy following which he was started on FOLFOX chemo regimen (folinic acid, 5-fluorouracil and oxaliplatin).

RESUMEN

Management of advanced intrahepatic cholangiocarcinoma (iCCA) is challenging and overall survival is poor. Progress in the development of new therapeutic options for metastatic cholangiocarcinoma (CCA) has been slow; hence, to date, there are no approved second-line agents in this setting. Although the development of immune checkpoint inhibitors has significantly improved overall survival in a variety of malignancies, there has not been a clinically important impact in CCA. This report presents a 66-year-old patient with chemotherapy-refractory iCCA who experienced a prolonged response to immunotherapy. Tumor genome profiling revealed a high tumor mutation burden of 17 mutations per megabase in the absence of microsatellite instability. He was started on immunotherapy with nivolumab and has experienced an ongoing response for 16 months without clinical symptoms and only minimal radiologic disease.

RESUMEN

CONTEXT: Recombinant human thyrotropin (rhTSH) has been shown to be an effective stimulation method for radioactive iodine (RAI) therapy in differentiated thyroid cancer, including in those with nodal metastases (N1 DTC). OBJECTIVES: To demonstrate the noninferiority of rhTSH vs thyroid hormone withdrawal (THW) in preparation to RAI regarding disease status at the first evaluation in the real-life setting in patients with N1 DTC. DESIGN: This was a French multicenter retrospective study. Groups were matched according to age (<45/≥45 years), number of N1 nodes (≤5/>5 lymph nodes), and stage (pT1-T2/pT3). RESULTS: The cohort consisted of 404 patients pT1-T3/N1/M0 DTC treated with rhTSH (n = 205) or THW (n = 199). Pathological characteristics and initially administrated RAI activities (3.27 ± 1.00 GBq) were similar between the two groups. At first evaluation (6 to 18 months post-RAI), disease-free status was defined by thyroglobulin levels below threshold and a normal ultrasound. Disease-free rate was not inferior in the rhTSH group (75.1%) compared with the THW group (71.9%). The observed difference between the success rates was 3.3% (-6.6 to 13.0); rhTSH was therefore considered noninferior to THW because the upper limit of this interval was <15%. At the last evaluation (29.7 ± 20.7 months for rhTSH; 36.7 ± 23.8 months for THW), 83.5% (rhTSH) and 81.5% (THW) of patients achieved a complete response. This result was not influenced by any of the known prognostic factors. CONCLUSIONS: A preparation for initial RAI treatment with rhTSH was noninferior to that with THW in our series of pT1-T3/N1/M0-DTC on disease-free status outcomes at the first evaluation and after 3 years.

RESUMEN

A total of 254 patients with stages T1-3a/N0-1/M0 operable breast cancer were randomized to either surgery alone or surgery plus adjuvant chemoimmunotherapy (LMF + BCG). Ten-year results are presented for RFS (relapse-free survival) and OAS (overall survival) in the whole patient population as well as in the most important menopausal and nodal subgroups. LMF + BCG significantly increased RFS in the whole patient population as well as in node-positive women. The earlier impressive RFS and OAS gains for node-negative patients were fading after 5 and 8 years respectively, leaving marginal trends in favour of the LMF + BCG treated women. Node-positive patients treated with LMF + BCG continue to demonstrate a marginal gain in RFS up to 10 years. This gain is nearly exclusively expressed in postmenopausal node-positive women, an observation which can be made in the node-negative patient group as well. Despite the still continuing increase in RFS,' no OAS benefit was observed for node-positive women with LMF + BCG at any time of the study. Dose still remains a critical factor in cancer therapy. However, at 10 years of follow-up, a full dose of LMF (greater than or equal to 90%) during the six cycles no longer affects OAS favourably. There was no indication of any adverse long-term toxicity of LMF + BCG in our study after a median follow-up of 10 years, especially no increase of second tumours. In the node-negative patient population, the presence or absence of intramammary lymphatic infiltration seems to be a significant prognostic factor within this nodal subgroup.

RESUMEN

Temperature-sensitive liposomes are designed to break down and release their contents preferentially at temperatures attainable by local hyperthermia. The antitumor effects of hyperthermia and anticancer drugs selectively delivered by temperature-sensitive liposomes in metastatic lymph nodes in rats were determined. Temperature-sensitive liposomes containing bleomycin (BLM) were injected sc into the dorsal surface of the right hindfoot of rats bearing AH66 ascites tumor implanted 7 days previously into a right popliteal lymph node. To break down these temperature-sensitive liposomes preferentially in the metastatic lymph nodes and to achieve the synergistic effects of local hyperthermia and BLM, we applied local hyperthermia to the right popliteal lymph node by making use of a water bath at 44 degrees C for 20 minutes. There was a significant difference in suppression of tumor growth and prolonged survival in rats receiving both temperature-sensitive liposomes containing BLM and local hyperthermia, compared with groups receiving hyperthermia alone, water solution of BLM alone, or a combination of both (P less than 0.05). The possibility that hyperthermia plus temperature-sensitive liposomes will enhance therapy for patients with metastatic lymph nodes warrants attention.

RESUMEN

In 24 patients with metastatic malignant melanoma, combined treatment with radiation and hyperthermia was administered to 38 localizations, radiation alone to 8 comparative localizations and hyperthermia alone to 3 localizations. Hyperthermia was administered during one hour by using a 433 MHz microwave generator. The heat treatment was given within 30 min following irradiation. Although an intratumoral temperature of 43 degrees C was aimed, considerable variations occurred during one session and from session-to-session. Radiation schedules consisted in either one large fraction (6-8 Gy) once a week in 14-21 days or two fractions (4-5 Gy) twice a week in 21 days. In the group of patients receiving irradiation once a week, three heat treatments were administered. In the twice-a-week radiation schedule, six heat sessions were given. The overall complete response (CR) rate in patients receiving combined treatment was 50%. In the group of patients treated with hyperthermia and irradiation schedules of 8 Gy per fraction, the CR rate was 83%. Irradiation alone achieved 38% CR rate but some of these CR relapsed during follow-up whereas the comparative area treated with radiation and heat remained under control at this time. The lesions treated with heat alone did not show any response to treatment. Enhancement of the acute skin reactions was generally observed. However, because the total doses were relatively low, this enhancement did not constitute a clinical problem. CR appears to occur more frequently in small tumor sizes. The highest and lowest temperature ever registered during any session of hyperthermia did not seem to correlate with the tumor response.

RESUMEN

A microwave heating apparatus with a frequency of 2,450 MHz and an inductive radio-frequency heating apparatus were developed for hyperthermia for cancer therapy, and clinical trials of combined radiation and hyperthermia were conducted. During the same period, a capacitive type radiofrequency unit was used. The tumors included superficial tumors, cancer of the uterine cervix, recurrent tumors at the stump of the cervix, and some deep-seated tumors. Cases showing complete response were as follows: 5 out of 13 cases treated with 2,450 MHz heating for superficial tumors, 8 out of 17 cases treated with 2,450 MHz intracavitary heating, and 2 out of 15 cases treated with radiofrequency heating. A feasibility study of various heating modalities was performed.

RESUMEN

Intralesional administration of emulsified croton oil into established syngeneic transplants of murine firosarcoma no. 1023 caused complete regression of the injected tumors in C3H mice without recurrence during the period of observation. In Sewall Wright strain 2 guinea pigs, in contrast to BCG cell wall vaccine which eradicated regional lymph node metastasis as well as dermal transplants, croton oil treatment only delayed the development of metastatic disease despite the fact that the injected skin tumors did not recur. 12-O-Tetradecanoylphorbol 13-acetate (TPA), the active principle of croton oil, incorporated in mineral oil droplets in aqueous suspension, caused regression of murine tumors when injected intralesionally. Aqueous suspensions of TPA failed to eliminate the tumors. Our results suggest that tumor regression induced by croton oil of TPA emulsions was due to indiscriminate destruction of the injected tissue.

RESUMEN

A series of 41 patients at the MGH who received 5-drug chemotherapy, cyclophosphamide, methotrexate, 5-fluorouracil, vincristine and prednisone, (CMF VP) as adjuvant to surgical treatment of operable breast cancer with 4 or more positive axillary nodes is compared to an analogous group of patients treated with cyclophosphamide, methotrexate and 5-fluorouracil (CMF) reported by Bonadonna et al. in an effort to assess the contribution of the treatment program to disease control. The MGH pattern of disease free survival closely parallels that of Bonadonna. Median disease-free survival among the 24 patients who have not recurred is 27 months; among those who recurred 18 months. The analogous medians for treated patients in the Bonadonna study are 24 months and 16 months, as compared to 27 months and 8 months for his nontreated controls. The treatment program, carried out over a two year period, was well tolerated with excellent patient compliance. There was no significant impact, however, in the disease-free survival of postmenopausal patients. While use of this regimen improved disease-free survival in premenopausal individuals, it is clear that a great deal of room for improvement exists, and newer regimens should be investigated.

RESUMEN

Using a co-ordinated multidisciplinary approach with surgery, radiation therapy, and chemotherapy, 14 out of 21 patients with metastases from osteogenic sarcoma were rendered free of disease for over two to over 18 months. Most patients had pulmonary metastases, two had bony metastases, and one had metastases in the iliac nodes. As part of this multidisciplinary approach weekly high-dose methotrexate was given and caused tumour regression in seven out of 15 patients. After all clinical evidence of disease had been removed high-dose methotrexate was administered every two to three weeks as maintenance treatment. To assess the efficacy of treatment the results were compared with those in a historical control group of 82 consecutive patients who developed pulmonary or other metastases. The results in the study group were significantly better. This experience may be similar to that in Wilms's tumour, where actinomycin D has increased the cure rate when administered as adjuvant therapy after treatment of localised or overt metastatic disease.
