Ocular and Periocular Metastasis in Breast Cancer: Clinical Characteristics, Prognostic Factors and Treatment Outcome

BACKGROUND

Breast cancer remains a leading cause of cancer-related mortality and morbidity worldwide. Ocular and periocular metastasis present as a rare but clinically significant manifestation. This study aims to explore demographics and clinical aspects of ocular and periocular metastasis in breast cancer patients.

METHODS

A retrospective cohort study comprising 45 breast cancer patients with ocular or periocular metastasis treated between 2013 and 2023. Patient demographics, tumor characteristics, diagnostic methods, treatment modalities, visual outcomes, and survival data were analyzed.

RESULTS

Among 9902 breast cancer patients, 0.5% developed ocular or periocular metastasis, constituting 2.4% of metastatic cases. The median age was 50 years. Ocular metastasis timing varied: 5% before breast cancer, 24% concurrent, 22% within a year, and 49% after. The most common presentations included incidental MRI findings (42%) and vision decline (31%). Metastasis involved the orbit (47%), choroid (40%), optic nerve (11%), and iris (2%), with 44% having bilateral involvement. Predictive factors included invasive lobular carcinoma (ILC) (p < 0.0001) and brain metastasis (p < 0.0001), with ILC exhibiting a sixfold higher likelihood of ocular metastasis than invasive ductal carcinoma (IDC). Primary treatment was radiation therapy (89%), yielding a 55% maintenance of excellent vision (<0.5), with 93% developing dry eye disease. Patients with ocular metastasis faced an increased risk of disease-related mortality (p < 0.0001), with 71% succumbing within 10 months post-diagnosis.

CONCLUSIONS

Ocular metastasis in breast cancer is rare (0.5%) but signifies poor outcome. It is linked to ILC and concurrent brain metastasis. Primary treatment involves radiation therapy, with a favorable visual prognosis.

Optic Nerve Metastasis in Lung Adenocarcinoma

In this article, we report a rare case of an optic nerve metastasis secondary to lung adenocarcinoma. The ocular manifestation was the first clinical sign of the disease, and further investigation led to the diagnosis of the underlying malignancy. A 59-year-old woman presented with progressive blurring of vision in the right eye for the past month. She had been having headaches for the past two weeks and left upper limb weakness for one day. She also had loss of appetite and weight for the past few months. She looked lethargic. On presentation, her bilateral eye vision was 6/18. Both anterior segments were unremarkable. Fundoscopy showed a normal optic disc in both eyes. A nervous system examination showed mild motor sensory impairment over the left upper and lower limbs and also impairment of cranial nerves V and VII. Brain computed tomography was conducted and revealed soft tissue lesions at the lateral aspect of the optic nerve and multiple recent cerebral infarcts. Brain and orbital magnetic resonance imaging showed a metastasis intraconal lesion at the right intraorbital segment of the optic nerve. CT thorax, abdomen, and pelvis were done. The finding revealed carcinoma of the left lung with distant metastasis. The patient's general condition deteriorated in less than two weeks. The family refused further intervention. The patient died three months after the initial presentation.

Prediction model of ocular metastasis from primary liver cancer: Machine learning-based development and interpretation study

BACKGROUND

Ocular metastasis (OM) is a rare metastatic site of primary liver cancer (PLC). The purpose of this study was to establish a clinical predictive model of OM in PLC patients based on machine learning (ML).

METHODS

We retrospectively collected the clinical data of 1540 PLC patients and divided it into a training set and an internal test set in a 7:3 proportion. PLC patients were divided into OM and non-ocular metastasis (NOM) groups, and univariate logistic regression analysis was performed between the two groups. The variables with univariate logistic analysis p < 0.05 were selected for the ML model. We constructed six ML models, which were internally verified by 10-fold cross-validation. The prediction performance of each ML model was evaluated by receiver operating characteristic curves (ROCs). We also constructed a web calculator based on the optimal performance ML model to personalize the risk probability for OM.

RESULTS

Six variables were selected for the ML model. The extreme gradient boost (XGB) ML model achieved the optimal differential diagnosis ability, with an area under the curve (AUC) = 0.993, accuracy = 0.992, sensitivity = 0.998, and specificity = 0.984. Based on these results, an online web calculator was constructed by using the XGB ML model to help clinicians diagnose and treat the risk probability of OM in PLC patients. Finally, the Shapley additive explanations (SHAP) library was used to obtain the six most important risk factors for OM in PLC patients: CA125, ALP, AFP, TG, CA199, and CEA.

CONCLUSION

We used the XGB model to establish a risk prediction model of OM in PLC patients. The predictive model can help identify PLC patients with a high risk of OM, provide early and personalized diagnosis and treatment, reduce the poor prognosis of OM patients, and improve the quality of life of PLC patients.

Choroidal metastasis and bilateral optic nerve involvement as presenting sign of metastatic lung adenocarcinoma: A case report

A 49‐year‐old male presented with a gradually progressive loss of vision in both eyes. Funduscopic examination revealed bilateral optic disc swelling and two yellowish elevated choroidal lesions in the left eye. Ophthalmic imaging raised suspicion of choroidal metastasis. Adenocarcinoma of the lung was detected in further systemic evaluation.

IRIS METASTASIS FROM BREAST CANCER SUCCESSFULLY TREATED WITH ABEMACICLIB AND LETROZOLE

PURPOSE

To describe a patient with an unusual presentation of iris metastasis from breast cancer and her response to systemic therapy.

METHODS

Retrospective chart review of one patient.

RESULTS

A 57-year-old woman presented with a superonasal translucent vascularized iris stromal mass with fish egg-like structures budding from the surface. High-frequency anterior segment ultrasonography demonstrated a solid iris stromal mass measuring 6.0 mm × 3.3 mm × 1.9 mm. On optical coherence tomography, the egglike structures appeared as hyperreflective spheres, some of which were detached from the main iris stromal tumor. Oncologic evaluation revealed metastatic breast cancer involving the brain and lung. She was treated with oral abemaciclib and letrozole, as well as external beam radiotherapy to the brain. The iris mass had completely regressed within 4 months and remained undetectable through the 8-month follow-up. The other metastatic lesions responded well to therapy.

CONCLUSION

A case of iris metastasis was reported as the presenting sign of cancer dissemination that was successfully treated with targeted systemic therapy without ocular radiotherapy.

Cytological Diagnosis of Ocular Metastasis of Squamous Cell Carcinoma Cervix

Ocular metastasis is considered a rare phenomenon. Metastatic spread of tumors in the eyeball is usually discovered only when it affects the visual acuity. In women, breast tumors are to known metastasize in and around the eyeball. Cervical carcinomas are rarely known to metastasize in the eyeball. We present here a rare case of ocular metastasis, diagnosed on fine-needle aspiration cytology, in a known case of squamous cell carcinoma of the cervix.

Clinical Significance of CYFRA21-1, AFP, CA-153, CEA, and CA-199 in the Diagnosis of Lung Cancer Ocular Metastasis in Hypertension Population

Purpose: To detect lung metastases, we conducted a retrospective study to improve patient prognosis.

Methods: Hypertension patients with ocular metastases (OM group; n = 58) and without metastases (NM group; n = 1,217) were selected from individuals with lung cancer admitted to our hospital from April 2005 to October 2019. The clinical characteristics were compared by Student's t-test and chi-square test. Independent risk factors were identified by binary logistic regression, and their diagnostic value evaluated by receiver operating characteristic curve analysis.

Results: Age and sex did not differ significantly between OM and NM groups; There were significant differences in pathological type and treatment. Adenocarcinoma was the main pathological type in the OM group (67.24%), while squamous cell carcinoma was the largest proportion (46.43%) in the NM group, followed by adenocarcinoma (34.10%). The OM group were treated with chemotherapy (55.17%), while the NM group received both chemotherapy (39.93%) and surgical treatment (37.06%). Significant differences were detected in the concentrations of cancer antigen (CA)−125, CA-199, CA-153, alpha fetoprotein (AFP), carcinoembryonic antigen (CEA), cytokeratin fraction 21-1 (CYFRA21-1), total prostate-specific antigen, alkaline phosphatase, and hemoglobin (Student's t-test). Binary logistic regression analysis indicated that CA-199, CA-153, AFP, CEA, and CYRFA21-1 were independent risk factors for lung cancer metastasis. AFP (98.3%) and CEA (89.3%) exhibited the highest sensitivity and specificity, respectively, while CYRFA21-1 had the highest area under the ROC curve value (0.875), with sensitivity and specificity values of 77.6 and 87.0%, respectively. Hence, CYFRA21-1 had the best diagnostic value.

Ocular Metastasis in Elderly Male Bladder Cancer Patients: Potential Risk Factors

Bladder cancer is a common type of tumor among elderly male population; it causes intraocular metastasis (IOM). The study investigated the differences between elderly male bladder cancer patients with and without IOM, and identified risk factors for IOM. In this study, 749 elderly male patients (aged ≥50 years) with bladder cancer were included from November 2003 to December 2016. Differences between the IOM and non-IOM (NIOM) groups were evaluated by chi-square test and Student’s t-test. The binary logistic regression analysis calculates the risk factors. Receiver operating characteristic (ROC) curve analysis was used to assess the diagnostic value of IOM in elderly male patients with bladder cancer.

The incidence of IOM in patients with bladder cancer was 1.7%. No significant differences were detected in age and histopathology between the IOM and NIOM groups. According to the study, the IOM group had higher ALP and Cyfra21-1. Binary logistic regression indicated that ALP and Cyfra21-1 were risk factors for IOM in elderly male bladder cancer patients (p < .05). ROC curve analysis revealed area under the curve values for ALP and Cyfra21-1 of 0.913 and 0.814, using cutoff values of 9.65 and 83.5 U/L, respectively. The sensitivity and specificity values for ALP were 61.5% and 95.8%, respectively, while those for Cyfra21-1 were 84.6% and 73.3%.

The investigation indicates that ALP and Cyfra21-1 are risk factors for IOM in elderly male patients with bladder cancer and ALP is more reliable at distinguishing IOM from NIOM in elderly male patients with bladder cancer.

Carbohydrate antigen-125, calcium, and hemoglobin as predictive clinical indicator for ocular metastasis in male liver cancer patients. Biosci Rep. 2020;40:BSR20194405. [PMID: 32090248 PMCID: PMC7040464 DOI: 10.1042/bsr20194405]

Background Primary liver cancer (PLC) is a common type of cancer among men worldwide. Little is known regarding the relationship of liver cancer with ocular metastasis (OM). Drinking has been also reported to be related not only to the occurrence of liver cancer but also to the causes of some ocular lesions. Purpose A diagnostic standard for the levels of serum biomarkers associated with OM derived from liver cancer in men is urgently needed. Material and methods We examined the association between OM in liver cancer and its serum biomarkers. A total of 1254 male patients with liver cancer were recruited in this retrospective study between July 2002 and December 2012. We assessed the relationship between drinking preference and OM in male patients with liver cancer, and aimed to identify an independent prognostic factor or establish a quantitative indicator for OM. Results By assessing the potential indicators, carbohydrate antigen-125 (CA-125), calcium, and hemoglobin (Hb) were found to be most valuable in the diagnosis of OM in male patients with liver cancer. Conclusion CA-125, calcium, and Hb are independent risk factors of OM in patients with liver cancer who consume alcohol.

Ocular involvement in metastatic and systemic malignancies is not rare

Background

Metastatic disease to the eye most commonly involves choroid followed by orbit leading to varied ocular manifestations. By comparison, it is relatively rarer than primary malignancies of eye as well as metastasis in other parts of the body.

Aim

The aim of this study is to evaluate the common eye and orbital structures involved in secondary ocular and metastatic disease, to describe its clinical manifestations and outline the management done.

Methods

A retrospective study of newly diagnosed cases of ocular metastasis in last 2 years conducted in our recently established department of ocular oncology at a tertiary eye care hospital in Nepal. Demography, age and sex distribution were noted. The patients were segregated into those with secondary or metastatic ocular malignancies. Detail study on the metastatic disease to eye was made in regards to presenting symptoms, signs, primary site of cancer, and the treatment done. Details of the investigations done, like biopsy and imaging were also recorded.

Results

There were a total of 28 patients, whose age group ranged from 9 years to 69 years with median age of 43 years. Females constituted 46% of total patients. Both the eyes were involved in 9 patients (32%). Eye was secondarily involved by paranasal sinus tumors and Non Hodgkin lymphoma (7 patients each). Ocular metastasis was commonly seen from broncogenic carcinoma in four and breast carcinoma in three patients. Simultaneous metastasis to other parts of the body was also seen in 61% of our patients. Diminution of vision in 49% was the most common presenting feature followed by proptosis in 16% and palpable mass in 14% of patients. Orbit in 43% cases is the commonest ocular structure involved. Histopathologic diagnosis was done in 32% only while rest was based on imaging alone. The most common treatment done was chemotherapy in 57% patients.

Conclusion

Ocular metastasis can display a wide variety of clinical and imaging features and therefore a high degree of suspicion is required. It is often associated with simultaneous metastasis to other parts of the body as well, hence the importance of earlier diagnosis and metastatic workup.

Risk factors and their diagnostic values for ocular metastases in invasive ductal carcinoma

Invasive ductal carcinoma (IDC) is a major type of breast cancer. Ocular metastasis (OM) in IDC is rarely seen, but patients with OM often have a poor prognosis. Furthermore, OM is difficult to detect in the early stages by common imaging examinations. In the present study, we tried to figure out the risk factors of OM in IDC and evaluate their diagnostic values for early detection. There were 1192 IDC patients who were divided into two groups according to ocular metastasis involved in this study. Clinical parameters of those patients were used to detect differences. The binary logistic regression test was then used to determine the risk factors of OM in IDC. Furthermore, ROC curves of both single and combined risk factors were established to examine their diagnostic values. The incidence of axillary lymph node metastases was significantly higher in the OM group (p = 0.002). Higher carbohydrate antigen 153 (CA153), lower apolipoprotein A1 (ApoA1), and hemoglobin (Hb) were risk factors for OM in IDC (p < 0.001, p < 0.001, p = 0.038, respectively). In the single risk factor ROC analysis, cutoff values of CA153, ApoA1, and Hb were 43.3 u/mL (CI: 0.966-0.984, p < 0.001), 1.11 g/L (CI: 0.923-0.951, p < 0.001), and 112 g/L (CI: 0.815-0.857, p < 0.001), respectively. Among the ROC curves of combined risk factors, CA153+ApoA1+Hb had the best accuracy, with the sensitivity and specificity of 89.47% and 99.32%, respectively (CI: 0.964-0.983, p < 0.001). CA153, ApoA1, and Hb are risk factors for OM in IDC. In clinical practice, the three parameters could be used as predictive factors for the early detection of OM.

Lung cancer and intraocular metastasis in gestation: Clinical experiences of a rare case

Lung cancer in pregnancy combined with intraocular metastasis rarely occurs and has a poor prognosis. Here, we report an extremely rare case of a 31-year-old non-smoking pregnant female who was diagnosed with lung adenocarcinoma with multiple metastasis including choroidal metastasis. Whole exon sequencing was performed but no appropriate therapeutic target was identified. The patient received standard pemetrexed plus carboplatin for first-line treatment after delivery. Ophthalmic treatment including transpupillary thermotherapy and intravitreal ranibizumab injections were administered and the patient responded very well to treatment. Her visual acuity was restored, indicating systemic therapy combined with ophthalmic treatment was an appropriate choice of therapy. KEY POINTS: SIGNIFICANT FINDINGS OF THE STUDY: The case reported here of a pregnant female diagnosed with lung cancer with choroidal metastasis highlights the aggressive characteristics of the disease. WHAT THIS STUDY ADDS: Systemic therapy in combination with ocular therapy is an appropriate choice of treatment.

Solitary late metastasis of primary renal cell carcinoid tumor to the extraocular muscles imaged with indium-111 octreotide

A 75-year-old male presented with right eye pain and proptosis. His history was significant for renal cell carcinoma treated with left nephrectomy 2 years previously. Computed tomography (CT) imaging demonstrated a 1.6-cm enhancing lesion in the right retrobulbar space. Surgical biopsy revealed a low-grade metastatic carcinoid tumor. At retrospective review, the primary renal lesion from 2 years prior was rediagnosed as consistent with a renal carcinoid tumor. Indium-111 octreotide single photon emission CT/CT imaging demonstrated a solitary metastasis within the right extraocular muscles. The patient subsequently developed additional metastases within the remaining right kidney and lung.

Alectinib in the treatment of ocular metastases of ALK rearranged non small cell lung cancer: Description of 2 case reports

RATIONALE

Choroidal metastasis is a rare metastatic location although the most common intraocular neoplasm. In general, choroidal metastases respond favorably to systemic therapy targeted toward the primary neoplasm. In patients with choroidal metastasis of ALK rearranged non small cell lung cancer (NSCLC), targeted therapy using Alk inhibitors gradually replaced radiotherapy as the best treatment. Alectinib is a second-generation ALK inhibitors. Here we describe 2 clinical cases of patients with choroidal metastasis of ALK rearranged NSCLC who received Alectinib as first-line therapy achieving disease control and quality of life improvement.

PATIENTS CONCERNS

In case report 1, 62-year-old man presented with scintillated scotomas at the level of the right eye; in case report 2, 69-year-old man presented with respiratory distress, persistent cough resistant to medical therapy, pain, and blurred vision.

DIAGNOSES

In case report 1, fundus and ultrasonographic examination showed circumscribed choroid thickening with dome-like appearance compatible with repetitive lesion. Computed tomographic/y (CT) showed multiple bilateral pulmonary nodular formations and adenocarcinoma of the lung was diagnosed by a transbronchial biopsy.In case report 2, CT showed a primary lesion of 36 × 27 mm in the middle lobe with bilateral lung metastases and lymphadenopathies. Multiple hepatic metastases and minor suspicious bone repetitions. A liver biopsy made a diagnosis of adenocarcinoma compatible with pulmonary primitiveness. An ocular fluoroangiography evidenced a left choroidal metastasis.

INTERVENTIONS

Case report 1, 2, medical treatment with Alectinib 1200 mg/day was initiated.

OUTCOMES

In case report 1, a few days after beginning the treatment, both systemic symptoms like respiratory distress and low vision were palliated. Reassessment by CT confirmed treatment response. In case report 2, clinically, visus disorders had already improved 2 weeks after beginning treatment. CT showed pulmonary, nodal, and hepatic response. Stability of bone metastases occurred after 2 months. In addition, ocular ultrasonography documented the regression of previously reported lesions confirmed treatment response.

LESSONS

Alectinib works very well in intracranial metastases and is assumed to be so on the ocular ones as well, with benefit for the patient in quality of life.

CA-125, CA-153, and CYFRA21-1 as clinical indicators in male lung cancer with ocular metastasis

Despite recent improvements in diagnosis and therapy, lung cancer remains the most common malignant tumor in males, with high morbidity and mortality. As the annual incidence continues to increase worldwide, the prognosis for male patients with lung cancer remains unsatisfactory. Interestingly, smoking is associated with lung cancer and ocular lesions by altering risk factors such as carbohydrate antigen (CA)-125, CA-153 and cytokeratin-19 fragment (CYFRA21-1). A diagnostic standard for serum biomarker levels of ocular metastasis (OM) in males with lung cancer is therefore urgently needed. In this retrospective analysis, we examined the relationship between smoking preference and OM in male patients with lung cancer to identify an independent prognostic factor or establish a quantitative indicated standard for OM using the clinical indexes from 2238 cases of male lung cancer. The combination of CA-125, CA-153 and CYFRA21-1 could help diagnose OM in male lung cancer patients. This finding might lead to more timely diagnosis and effective therapies.

CEA as a risk factor in predicting ocular metastasis from colorectal cancer

Objective: Colorectal, closely following pulmonary and breast, is the third predilection site of cancer that lead to death all over the world. Ocular metastasis (OM) of colorectal cancer (CRC) is becoming increasingly common and presents a poor prognosis. In this study, we detected some recognized tumor biomarkers and tried to differentiate the discrepancy between CRC patients with and without OM in order to clarify the risk factor for OM in patients with colorectal cancer. Methods: 1735 patients with colorectal cancer in total from August 2005 to August 2017 were involved in this study. Nonparametric rank sum test and Chi-square test were applied to prescribe whether there were significant differences between OM group and non-ocular metastasis (NOM) group. And binary logistic regression analysis was used to determine the risk factor. Then, we used receiver operating curve (ROC) to assess the diagnostic value of OM in CRC patients. Results: The incidence of OM in CRC patients was 1.12%. No significant differences were found in gender, age, histopathological type, tumor classification and tumor differentiation between OM group and NOM group. Nonparametric rank sum test approved that OM group had higher serum CEA level compared with NOM group. Binary logistic regression indicated that CEA was a risk factor for OM in colorectal cancer patients (p<0.001). ROC curve showed that AUC of CEA was 0.877. The cutoff value of CEA was 12.45 ng/ml, whose sensitivity is 1.000 and its specificity is 0.877. Conclusion: Based on our study, CEA was a risk factor of ocular metastasis in colorectal cancer patients.

Isolated Unilateral Infiltrative Optic Neuropathy in a Patient with Breast Cancer

Metastasis to the optic nerve is very rare. We report a case of metastatic breast cancer to the optic nerve head without the involvement of other ocular or orbital structures. The patient, a 39-year-old female who had been previously treated for breast cancer, reported a gradually progressive decrement in visual acuity of the right eye during the past two months. Fundus examination of the affected eye revealed swelling of the optic disc which was infiltrated by a yellowish mass. Further evaluation using optical coherence tomography and fluorescein angiography showed optic disc swelling. Magnetic resonance imaging revealed no pathologic findings. With a diagnosis of unilateral infiltrative optic neuropathy, we referred the patient to an oncologist for further evaluation.

Optic nerve head problem

A 68-year-old woman with a recent history of blurring in the left eye had undergone mastectomy for breast cancer 20 years ago. A series of bone metastases started 5 years after her diagnosis. Examination of the optic nerve head of the left eye revealed an isolated peripapillary mass. Indocyanine green angiography displayed vessels within the mass, and fluorescein angiography demonstrated hyperfluorescence of the mass from vascular leakage plus lobular spots of blocked fluorescence. B-scan ultrasound revealed a hyperechoic-elevated nodular mass on the optic disc. Spectral-domain optical coherence tomography displayed a mass of spherules. Magnetic resonance imaging of the brain demonstrated metastatic tumors. She was diagnosed with an optic disk metastasis from her breast carcinoma.
